There are six of this Flak bunkers in the battery, some of them having the Flak position on top of the bunker while others like this one have an emplacement for 2 cm besides it. It is probably a naval redesign of the 501.
Recently excavated by the CIOS. The granite walls are German made.
We were allowed to enter.

The one at the seaside.
And a hidden one.
One with an extra observation post.
