I've started a new board for sites that we'll see on the Committee on Design: Origins of Modernism - Berlin, September 22 - 28, 2013, tour starting next week. Please check back often; I'll be adding to this board each day until the conference. And you - what do you love to visit in Berlin, or want to see in person?
