2WJ9+VJ Kronstadt District, Saint Petersburg, Russia

North Battery No. 7 – the closest to the Sestroretsk shore.
The structure includes four standard casemated traverses connected by earthen ramparts. During the construction of the water protection facilities, the battery was connected to the dam, and a construction equipment parking area was located in its vicinity.
In addition, a new pier was built in the harbor, from which a road was cut directly through the earthen rampart. Despite this, the overall state of preservation here was quite high, and “Number Seven” was for a long time one of the best sites for the possible organization of a coastal defense museum. Currently, all metal parts at the North Sea Battery No. 7 have been destroyed.
