the hardest thing is to spot them. Some are turned into museum and can be seen by any tourist, others are very visible, but some are only to be found if a local takes you to the place. The best"camouflaged" one was one right down town which was covered with timber and looked like a two dimensional wall behind a playground whereas there is in fact a large bunker behind the wall that is used as a shed. It is surrounded by brick houses that are prewar, so I had no clue there was abunker there. I even saw one used by a french fries vendor. I have pictures of all of these but it takes time to post them. I will a.s.a.p.
