An operating military unit on Kotlin Island (where Kronstadt is situated).
The first impression is that the unit was abandoned a dozen of years ago…
There are five buildings on the whole territory.
The building is divided into two parts, and from one part you can’t enter the other one. The first part is abandoned, there used to be a driving school here.
“Main routes schemes”
Another part of the building – here was a coastline anti-ship complex.
