The Mining School, the oldest higher technical educational institution in Russia, was founded in 1773 by decree of Catherine II. The school was located on the Neva embankment, in two buildings purchased from Count Pyotr Sheremetev. Initially, among others, the school enrolled students of Moscow University with some knowledge of arithmetic, geometry, chemistry, Latin, French, and German. The first mining officers finished school in 1776.
In 1804, the Mining Cadet Corps was established on the school basis and in 1806-1811, a group of Empire-style buildings designed by Andrey Voronikhin were constructed on the same land plot. The main facade overlooking the Neva was decorated with a twelve-column portico. The both sides of the portico were adorned with such statuaries as The Abduction of Proserpine by Pluto by Vasily Demut-Malinovsky and Hercules Strangling Antaeus by Stepan Pimenov. The side wings of the building featured two friezes by Demut-Malinovsky: Apollo Comes to Vulcan for his Chariot and Venus asks Vulcan to Forge an Armor for Mars.
In 1816, the Mining Cadet Corps received a collection of 3,400 samples of fossils from the Imperial Hermitage. Most of the items were from the mineral cabinet of Empress Catherine II. This collection marked the beginning of the Mining Museum. Nowadays, the Mining Museum with its unique collection of minerals is considered one of the largest museums of its kind in the world. Its funds number 240 thousand exhibits.
In 1834, the Mining Cadet Corps was reorganised into the Institute of the Corps of Mining Engineers and in 1866, into the Mining Institute. The Institute became an open higher educational institution with a five-year term of study. Upperclassmen were officially called students and no longer received the rank of a noncommissioned officer. At the same time, the student still wore the colours of the mining department. The Institute library boasted up to 28 thousand titles of books. 
Thirty years later, the Institute was named after Catherine II and in the 20th century, it repeatedly changed its name and status. For example, in 1956, the Institute was named after one of the founders of the Russian Social Democratic Labour Party Georgy Plekhanov who had studied at the Mining Institute in 1874-1876. In 2016, the Mining Institute received the status of a University and was renamed after Catherine II.
The Institute graduates include academicians Alexey Borisyak, Aleksandr German, Vladimir Obruchev, a discoverer of the Verkhnekamsk deposit Pavel Preobrazhensky, Baron Pyotr Wrangel, one of the founders of Russian volcanology Sofia Naboko, Director of the Leningrad Branch of the RAS Institute of Oceanology Raisa Demenitskaya, historian Felix Lurie, and many other prominent historical figures and scientists.

In the late 18th century, at the corner of Kosaya liniya and Kozhevennaya liniya there was a tannery of merchant Fyodor Yamshchikov. In the next century, the two-story building was no longer the tannery and was used as housing for workers. In 1905-1906, the building was remodelled to add four more floors according to the design of Vladimir Lipsky. With biting irony, this building was commonly called the Skobsky dvorets/Skobsky Palace. Living conditions in the “Palace” were far from ideal: most flats had even no kitchens, and out-of-town workers could not afford to rent a flat and had to make do with rooms and lodgings. The origin of the word “Skobsky” is obscure. The friendliest versions are that either the building owner was some Pskov merchant or the workers living in the building were from Pskov province. The least generous versions (like Vadim Shefner’s Motorny dom/Motor House) convey the general feeling of the district’s deprivation in the first half of the 20th century.

In June 1803, a professional fire brigade was organised by decree of Emperor Alexander I. According to this decree, a fire brigade was set up at each police station. Initially, wooden towers were added to the buildings housing the fire brigades. Later, they were replaced by proper fire watchtowers. One of the most striking examples of such architecture is the watchtower of the Vasilyevskaya Fire Station.
In 1882, the City Council decreed to construct the Vasileostrovskaya (Vasilyevskaya) Fire Station. The new building was to replace the dilapidated assembly house (the combined building of the police department and the fire house) in the 8th liniya. 
On the outskirts of Smolensk pole, an urban land plot was allotted for the fire station and the police department (at the corner of Bolshoy prospekt and the current 21st liniya). Both red brick buildings were completed by 1884 according to the design of civil engineer Vladimir Shalamov. 
There were outbuildings at the back of the plot. The fire station had a stable. On the ground floor of the station there were rooms to make a fire train, to store uniforms and gear, as well as a drying room, a dining room, and a kitchen. The firefighters themselves lived on the first floor.
Since 1957, the building housed the first Fire Technical Museum in the country. In 1965, a permanent Fire Technical Exhibition was opened in the building. Seven years later, it was headed by Boris Konchayev, a retired head of the Leningrad Fire Department (he held this post for 24 years).
In 1995, in front of the fire station, a monument was erected to the firefighter heroes who defended Leningrad and died in the line of duty during the Siege of Leningrad and the Great Patriotic War. To this day, the Fire Technical Exhibition named after Boris Konchayev welcomes its visitors.

The life of Sofya Kovalevskaya, the first female mathematician in Russia, the world’s first female professor of mathematics, the author of numerous scientific works on physics and mathematics is closely connected with St. Petersburg and Vasilyevsky Island. Although, the street named after her is now located in a completely different part of the city.
From early childhood, the girl showed talent for mathematics and at the age of 16, Sofya Korvin-Krukovskaya left to study in the capital. However, in those days, a girl could not get a higher education in Russia and could study abroad only with the permission of her parents or her husband. Therefore, Sofia resorted to a desperate move by contracting a fictitious marriage with a young scientist-geologist Vladimir Kovalevsky. After that, she entered the University of Heidelberg in Germany where in 1874 she passed Ph.D. defence and earned the degree of Doctor of Philosophy. Returning to St. Petersburg, Kovalevskaya was not allowed to teach at St. Petersburg University: even with the academic degree, she could only teach mathematics to girls at a women’s gymnasium. Sofia was so disappointed that for six years she stayed away from mathematics and tried to find herself in literature.
The young scientists who returned to Russia and whose fictitious marriage grew into a real family needed material resources for their scientific activities and research. In 1877, the Kovalevsky couple moved to the house of Sophia’s mother, general’s wife Elizaveta Korvin-Krukovskaya (17, 6th liniya V.O.). At the time, it was a one-and-a-half-story stone mansion. In May 1877, the construction of a five-story wing for renting began in the courtyard of their house. For a while, renting the flats allowed the spouses to stay afloat and continue their scientific activities. Later, the house was passed over to Sophia’s sister Anne Jaclard, an activist of the Paris Commune. The flats were rented by famous historians, teachers, and academics. For example, future academician and orientalist Sergei Oldenburg lived in this house in the 1880’s-1890’s. However, in the early 20th century, the building was remodelled and a five-storey rental house was constructed in its place for public officer Dmitry Ivanov whose monogram still remains on the leaves of the main entrance. In this house, the future poet and prose writer Vadim Shefner spent his childhood and youth.
Bolstered by the successful renting of flats in the 6th liniya, the Kovalevskys borrowed money for construction and in 1878-1879 began constructing a rental house in the 9th liniya, with baths in the courtyard, according to the design of Pavel Syuzor. But the investment did not pay off, only ruined its owners. The house was sold. The so called Andreyevskiye bani/Andreyev Baths have not survived to this day — they were torn down in the 1980’s. For many years, the house was associated with science: from the 1970’s to 2012, the AkademKnigi store was located in its basement.

In May 1727, a 20-year-old mathematician of Swiss origin Leonhard Euler, who later became one of the greatest mathematicians in history, came to the newly founded St. Petersburg Academy of Sciences. In his lifetime, he published more than 850 papers on mathematical analysis, combinatorics, graph theory, differential geometry, number theory, celestial mechanics, mathematical physics, optics, ballistics, shipbuilding, music theory, and more.
The great mathematician came to St. Petersburg in 1727 following the famous Bernoulli family. However, in 1740, after the death of Empress Anne of Russia, fearing instability, he decided to leave Russia. His resignation was accepted by the Academy in May 1741, and remaining an honorary member of the Academy with a salary of 200 rubles, the scientist went to the Berlin Academy of Sciences in Prussia.
Later, Euler returned to Russia when Catherine the Great ascended to the throne, who perfectly understood the magnitude of his genius. The Empress invited the scientist to work in St. Petersburg again, agreeing to all his conditions and promising to reorganise and patronize the Academy of Sciences. Catherine II also financed the purchasing of a house near the St. Petersburg Academy of Sciences, where Euler lived from 1766 to 1783. A memorial plaque was installed at 15, naberezhnaya Leytenanta Schmidta and since the 1920’s, there has been a school in the building.
In total, Euler lived in Russia for more than 30 years and was buried at the Smolensk Lutheran Cemetery/Smolenskoye kladbishche, from where he was transferred to the 18th-century Necropolis in the Aleksandr Nevsky Lavra. In 2007, to mark the 300th anniversary of the scientist, a bust was installed at 10, Pesochnaya naberezhnaya (where the Leonhard Euler International Mathematical Institute is located) and in August 2021, a garden square in the 10th liniya V.O. was named after the great mathematician.

After the assassination of Alexander II, the St. Petersburg Germans who historically lived on Vasilyevsky Island decided to open a new men’s hospital to immortalise the tsar’s name. In the 1880’s, the German Charitable Society acquired a land plot in the 15th liniya V.O. to construct the hospital. A small hospital was built in 1884 and called the Alexander Men’s Hospital established by citizens of the German Empire. The hospital had a personalised approach to patients and stringent requirements for employees: for example, they had to speak at least three languages (German and Russian were mandatory). Poor people of any nationality were treated free of charge. 
A short-lived but vibrant fashion for Art Nouveau in St. Petersburg left its mark in the 16th liniya V.O. — in the form of an asymmetric rental house of the Alexander Men’s Hospital. A four-story austere building with Gothic motifs was constructed by order of the German Charitable Society, which owned the hospital at that time. The budget of the medical institution was replenished by regular rent payments. The construction was commissioned to architect Alexander Gimpel in 1908. The house built to the customers’ liking was lined with moulded bricks brought from Frankfurt am Main. A small front garden stretches along the facade overlooking the liniya. Famous tenants of the spacious flats in this house included meteorologist Alexander Shenrok and Minister of Public Education, lawyer Lev Kasso. 
With the World War I outbreak, the hospital fully switched to the Russian language and the mention of citizens of the German Empire disappeared from its name. Later, the Alexander Hospital was converted into a psychiatric facility and in 1931, academician Ivan Pavlov opened a neurological clinic on its basis.

The monumental ensemble of the Dmitry Ott Research Institute of Obstetrics, Gynaecology and Reproductology occupies the very heart of the Spit of Vasilyevsky Island. It is situated in place of the former Kollezhskaya ploshchad between the Exchange, the Kunstkamera, and the buildings of St. Petersburg State University and the Academy of Sciences. 
The Obstetric Institute founded on the initiative of Empress Maria Feodorovna was located in the ancient mansion of Countess Zubova, on the bank of the Fontanka for almost a hundred years. It was then that Nestor Ambodik-Maksimovich worked here. He was an obstetrician extraordinaire, a personal doctor of Catherine the Great and one of the first paediatricians in the country. 
After studying obstetrics abroad and passing exams to confirm his qualifications at the Medical College, Nestor began medical practice at St. Petersburg Maritime Hospital and gave obstetric lessons at other medical institutions in St. Petersburg. In 1781, Ambodik-Maksimovich headed the training of midwives at the capital’s “midwives’ school”. The obstetrician achieved great success in developing midwifery, significantly reducing the mortality rate from parturient fever, the main problem of parturient women at that time. Ambodik-Maksimovich also paid much attention to children’s health, so he was considered one of the first Russian paediatricians. In the last years of the reign of Catherine II, he made a plan to develop obstetric training and reorganise obstetric care in Russia. When Paul I ascended to the throne, Ambodik’s career began to fail, he was banned from teaching and was put in charge of the maternity ward at the Kalinkin Hospital (aka Secret Hospital), the first venereological clinic. However, falling from grace with the Emperor did not prevent the professor from helping organise the Obstetric Institute. After the death of his father, Alexander I raised the doctor to the rank of state councillor, but Ambodik never returned to his professorship. He almost entirely retired from medicine and devoted his time to heraldry.
In 1893, Dmitry Ott became director of the Obstetric Institute. After graduating from the Imperial Medical and Surgical Academy (now the Military Medical Academy), he was sent to study abroad to improve his knowledge of obstetrics and gynaecology. Returning to Russia, in 1893 Ott headed the Imperial Clinical Obstetric Institute and became a life obstetrician of the Imperial Court. In 1895, he delivered a baby (Olga Nikolayevna) of Empress Alexandra Fedorovna in Tsarskoye Selo. In 1902, Ott operated on Olga Knipper-Chekhova, Anton Chekhov’s wife.
As a director of the Obstetric Institute, Ott enlisted the support of the royal family and decided to modernise and expand the institution to make it as good as the best clinics in Europe. Having collected all the ideas and comments on the design of a new complex of buildings, well-thought-out by Ott, architect Leont Benois began the construction. In February 1904, a new building of the Imperial Clinical Obstetric Institute was opened. The new building was unique: from the arrangement of wards and its own power plant to spacious and bright operating theatres. Two or even three operations could be carried out simultaneously in them and could be observed by students from the amphitheatre. A pipe organ was installed inside the building for therapeutic purposes: each patient had a telephone set at the bed and could pick up the phone to listen to organ music. In 1917, the organ was no longer used in medical practice and in 1931, the instrument was moved to Leningrad Philharmonic.
From 1899 to 1906, Ott served as director of St. Petersburg Women’s Medical Institute (now the First St. Petersburg State Medical University). For more than 40 years, Dmitry Ott conducted research and teaching activities, developed the training of obstetrician-gynaecologists, and cultivated outstanding scientists. Ott also made valuable contribution to operational medicine: he actively introduced aseptics and performed the first laparoscopic surgery. In recognition of his services, the Institute of Obstetrics and Gynaecology of the Russian Academy of Medical Sciences was named after Dmitry Ott.

In the first decades of St. Petersburg’s existence, the French Quarter sprang up in the 2nd and 3rd liniya V.O. It was inhabited by craftsmen and artists invited from France and Germany, who greatly contributed to the development of the young capital. Jean-Baptiste Alexandre Le Blond, an architect and landscape gardener invited by Peter I in 1716, also lived in the French Quarter. From that year until his death in 1719, he was the chief architect of St. Petersburg and drew up a Master Plan which envisioned the city centre to be located on Vasilyevsky Island. In 1716, he prepared a standard design of a residential building for noble citizens. The implementation of this project has survived to this day: in 1720-1726, architects Domenico Andrea Trezzini and Leonard Theodor Schwertfeger built a house according to Le Blond’s drawings at the start of the 7th liniya (its modern number is 12). French cutters, foundrymen, locksmiths, carpenters, and blacksmiths with their families and apprentices came to St. Petersburg, some of them along with Le Blond.
In the 1720’s, a road was laid from the Menshikov Market located in the current Rumyantsev Garden/Rumyantsevsky sad to the French Quarter. Only in 1871 it received its official name Solovyovsky pereulok (after homeowner, gold industry entrepreneur, and philanthropist Stepan Solovyov). The French Quarter existed for several decades, leaving no traces in the city toponymy. The Main Building of the Academy of Arts is kind of a historical reminiscence of the Quarter’s creative spirit. Its construction began in 1764 according to the design of French architect Jean-Baptiste Michel Vallin de la Mothe. Nowadays, this is the St. Petersburg Repin Academy of Fine Arts. The former Solovyov pereulok was also named after the painter — now it is ulitsa Repina.

In 1870, in the building of the Vladimir County School, the first university-type courses were opened, which could be attended by women equally with men. The academic staff included professors of St. Petersburg University such as physiologist Ivan Sechenov, chemist Aleksandr Borodin (who went down in history as a composer and participant of the Mighty Five), botanist Andrey Beketov, chemist Dmitry Mendeleev, and historian Konstantin Bestuzhev-Ryumin. The courses existed until 1875. Three years later, the founders of the Vladimir courses, Nadezhda Stasova, Maria Trubnikova, Varvara Tarnovskaya, and Anna Filosofova, with the assistance of Beketov, obtained permission to open Higher Women’s Courses in St. Petersburg. Historiographer and source-study expert Konstantin Bestuzhev-Ryumin was appointed the first director of the courses; in his honour the courses were unofficially called “Bestuzhev’s.” The grand opening of the Courses took place in September 1878 in the building of the Alexander Gymnasium on Gorokhovaya ulitsa.
As a private institution, the courses were funded mainly by a specially created Society for Funding the Higher Women’s Courses. In addition, a grant of three thousand rubles was provided from the Ministry of Public Education and St. Petersburg City Council. The courses offered paid education, but many teachers who had deep sympathy with the idea of women’s education worked free of charge.
The courses had such faculties as history and philology, physics and mathematics, and law (since 1906). The faculty of physics and mathematics was originally divided into physics and mathematics and special mathematics departments.
After the 1905 revolution, the Higher Women’s Courses received autonomy: the Council of Professors could choose the director from among their ranks and the educational process was reorganised. At the courses, a new subject system was introduced, which allowed students to select lecture courses, and teachers to expand the system of practical training. In 1910, the State Council recognised the Bestuzhev Courses as a higher educational institution providing education equal to that of a University. Therefore, a certificate of graduation of the Higher Women’s Courses was equated to a University degree. 
Initially, the courses enrolled women of 21 years or older with secondary education and later gymnasium graduates without age limit. The courses graduates could teach senior classes at women’s gymnasiums — since 1901, senior classes at women’s institutes — since 1903, junior classes at men’s educational institutions — since 1906, and at universities — since 1915.
In the 1890’s, two separate buildings were constructed for the Higher Women’s Courses in the 10th liniya V.O. as designed by Academician of Architecture Aleksandr Krasovsky. In 1902-1903, Vladimir Pyasetsky and Sergey Pokrovsky constructed a new building along the eastern border of the site. Another building whose main facade overlooked Sredny prospekt appeared in 1913-1914. The building was designed by Vladimir Tseidler in neoclassicism style.
In 1918, the Bestuzhev Courses were reorganised into the Third Petrograd University, which merged with the First Petrograd University in September of the following year. The building in the 10th liniya went over to the faculty of mathematics and mechanics, and the building on Sredny prospekt to the faculty of chemistry. Now it is occupied by the Interfaculty Training Centre of St. Petersburg State University.
The graduates of the Bestuzhev Courses included radiochemist Maria Pasvik, aerologist Tatiana Klado, teacher Julia Fausek, revolutionaries Konkordia Samoilova and Nadezhda Krupskaya, actress and ballet historian Lyubov Blok, writers Ekaterina Balobanova, Anna Chertkova, and Olga Forsh.

The first wooden church of the Annunciation of the Blessed Virgin Mary was built between the 7th and 8th liniya V.O. by 1741 with funds of wine tax farmer Irodion Chirkin. In 1750, the construction of a new stone church began to the south of it. It was financed by the same Irodion Chirkin and his son Ivan. The construction of the Baroque-style building took a lot of time: the first side-chapel was consecrated in 1762 and the bell tower was erected only in the 1790’s. The finished church could accommodate about five thousand people. In 1859, Academician of Painting Roman Vinogradov decorated the church with ornamental painting. Three years later, on the occasion of its centenary, the Society for Assistance to the Poor was created under the church. It operated an alms-house, a school, and a girls’ shelter. In 1870, a parsonage (70, 7th liniya) for priests was completed under the church.
In 1936, the church was closed and the icons were destroyed. The church was reinstated in 1992.

Историческая справка

In the 1880’s, a part of Smolensk pole between the 25th liniya V.O. and Klubny pereulok was given over to a public garden. Already in 1886, a wooden building of Vasileostrovsky Theatre for Workers was built in the centre of the garden according to the design of Karl Anderson with funds of Vasileostrovsky manufacturers. Despite the design simplicity, both the theatre building and the garden fence harmonised stylistically with the surrounding ensemble — the Exchange Merchant Hospital in the 24th liniya and the Red Cross shelter. The theatre staged performances based on the works of modern classics: Emile Zola, Anton Chekhov, and Maxim Gorky. On Sundays and holidays there was paid admission, and on other days, admission was free. 
In the 19th century, the garden occupied only the southern half of its current territory due to plans to create another street between Bolshoi prospect and Sredny prospekt. The northern part of the garden appeared only after the Great Patriotic War. 
In 2010, a monument to painter and public figure Nicholas Roerich was installed at the western entrance to the park.

Историческая справка Рисунок к КП 545

The first Russian business contacts with Werner von Siemens were established by engineer colonel Karl von Lüders who was sent to Berlin in 1849. He purchased four telegraph sets and 30 versts of isolated gutta-percha telegraph wire from Siemens & Halske for testing on St. Petersburg-Moscow telegraph line under construction. Subsequently, Siemens & Halske played a vital role in implementing all telegraph projects in the Russian Empire in the 1850’s, and Karl Lüders headed the telegraph office in 1866.  
In 1853, Siemens & Halske opened a St. Petersburg branch, which was headed by Karl, Werner’s younger brother. The company launched the construction of the Russian telegraph network. The large order brought a significant financial success to the company founded in 1847.
In the spring of 1879, Karl Siemens purchased two land plots in Kozhevennaya liniya with access to the bay and started the construction of Russia’s first cable plant. Creating the plant accelerated the city electrification replacing gas lighting from the streets of St. Petersburg. In addition to the cable plant, the Siemenses developed the production of lamps and copper mill products. Three enterprises were called Joint Stock Company of Russian Electrotechnical Plants Siemens & Halske.
In 1914, the plant was nationalised and reoriented its production to fulfil orders of the Military and Naval Departments. After the nationalization in 1918, the company began to bear the familiar name Northern Cable Plant.
Production grew, the country was actively electrified according to the GOELRO plan, and cables were needed more than ever. Sevkabel products were widely used to construct the most important hydroelectric power plants in the Soviet Union, metallurgical plants, and the Moscow Metro. During the Second World War, the plant workers accomplished a feat by providing the besieged city with electricity. The plant manufactured the armoured “life cable.” It was laid by the Ladoga military flotilla along the bottom of the Lake Ladoga to the Volkhov HPP. In the post-war years, Sevkabel continued to develop unique projects, lay underwater cables, and connect distant points with lines. For example, an iceberg-protection cable was developed for the Arctic. In 1949, the Sevkabel Research Institute was established next to the plant in Kozhevennaya liniya.
Already in the 21st century, the Sevkabel management decided to modernise the company structure and logistics, vacating the territory in Kozhevennaya liniya. In 2017, some more than century-old vacated historical buildings on the bay shore were given over to create the cultural and business space Sevkabel Port.
