Sj-4. Concrete ruins

In January 1940, the bunker has got a lot of direct hits of heavy shells, the western casemate was destroyed and roof of the shelter was damaged. During the second Voroshilov's storm of February 10 it had already represented the concrete ruins, rather than fighting structure. There were only 16 people in the ranks from the company of bunker's garrison.
Ruined passage to the former western casemate is on the photo.
