over here in hamburg there are still many of those airraid bunkers.they are so incredibly tough that they havnt been torn down after the war, and are now used for lotsa different stuff like the most impressive bunker in hamburg: the former air defence center.its a fkn huge concrete monster over at the heiligengeistfeld. with 4 big platforms on top of it, you can exactly see where the 4 big 128mm twin flakguns stood.its a mediacenter now with lots of advertise agencys, photographer studios and so on.its kinda strange feeling when ur walking up those steps, when u know that 60 years ago on the very same spot young ppl hurried upwards to man their guns, or when ur driving with the elevator wich was used to transport the heaps of ammo for the guns.
