Brandenburger Tor then and now
an installation called 180gradberlin ("180degrees Berlin" -- they have a great website, in German) -- showing a huge panorama of the site in 1945. I wish this thing could be put up in cities across North America to get it into people's heads just what happens when they send their war machines in to "soften" targets with bombs. Very powerful. Other cities in this project include Coventry, Stalingrad, Rotterdam, and Warsaw.
