Powder magazine on the right flank of the battery №3

The construction alongside with lighting and alarming systems has an advanced ventilation system and seems to be in quite good condition. Everything here is securely locked and seemingly even sealed. The cellar has a curious stone-brick structure, which is clearly seen in the picture. Originally, it was built with stone, but the rapid development of artillery in the 1870-80 required reconstructions and apparently brickworks is an example of this reconstructions.
