Defence structures made of concrete are located in the vicinity of Pogrankondushi village and can be seen as interesting objects of the military history. They were built in the end of the 1930s as a part of the USSR defence system.
The structure situated 2 km from Pogrankondushi is а concrete building with а one-storey aboveground part and а two-storey underground part. The walls have embrasures for artillery shooting. The dominating position of the structure on the hill provided good conditions for covering а large area with shells.
