The visit to the flak tower was well worth it, however I felt that more emphasis/explaination of where we were within the structure should have been made as opposed to a lot of history surrounding construction and the war in general being given out. That said, the guide was very knowledgeable.
This tour was well worth it. There was lots to see and we were guided by a very knowledgeable person who explained everything very well, with the emphasis being on the bunker itself, with only background info about the war being given out. Much better than the flak tower tour!
