Gorodomlya Island at a Glance

About Gorodomlya Island

Gorodomlya Island is an island in Lake Seliger in Tver Oblast, western Russia. It is notable for having hosted a Soviet research installation focused on aviation and rocketry in the post-World War II period.

The site contains former research facilities and associated buildings that were part of Soviet technical programmes; it is primarily known for that 20th century technical and military research role rather than as a recreational destination.

After 1945 the island became a centre for secret or classified research activities, including work that involved German specialists relocated to the Soviet Union; much of that activity dates to the immediate postwar decades.

The island lies within Lake Seliger in Tver Oblast, in western Russia, and is part of the lake’s island group within the regional inland lacustrine landscape.
