Memorial to the dead who in their last breath tried to cross the Berlin Wall (just the ones in Berlin, not from the border between East and West Germany), near Haus am Checkpoint Charlie, a very amazing museum.
Each cross has the picture and name of person who died from that monstrosity. For the most part, in Mitte you won't see any trace of it. Remnants can be found all over the city, though.
Because some of the bodies were not returned to families...
Museum of Fine Arts Houston
The complete inscription reads, "MUSEUM OF FINE ARTS ERECTED BY THE PEOPLE FOR THE USE OF THE PEOPLE" it is inscribed over the original entrance to the Museum of Fine Arts Houston.
