I like exploring these bunkers but this is one of the more boring ones. Its not unique in any way, just a lot of mosquitoes and trash. I would suggest visiting it but its nothing special.
A large bunker in good condition that has been excavated into the rock.
There is a bunker like this in the middle of nice nature. It's easy to head from Turku for a short forest trip, it's not a long distance
