One more example of installation of the Line - bunker #212. Big excavation with fosses for mg-embrasure and for entrance has been made in granite knoll. Than after inner partititions construction it has been covered by thick concrete roof. The granite slopes of the knoll serves as walls of such bunker. If it's embrasure is overgrown, it is not easy task to spot it. You'll find it only when you climb to it's roof.
