60.458286, 22.294929 (OpenStreetMap, Google Maps, Yandex Maps)

Streets in one of Turku’s districts are named after virtually all international acts of this kind adopted before the 1990’s. There are only two exceptions. We cannot say anything about the first one, as far as the second one goes, particular cultural and historical links played their part, so it was decided to monumentalise the larger object. This street described in this riddle is very far from the city centre, so you should find the street the name of which starts with the first and last letters of the street described above and contains the minimal number of letters from all the eligible streets. House No. 7 in the target street.
