Bebelplatz
A square just off the Unter den Linden, made famous as the Berlin site of Nazi student book-burning on the night of 10 May 1933.
In 1995 an interesting memorial was built on the site. It is a small, bare underground room, with empty bookshelves lining the walls: enough to hold the 20,000 books burned that night. The room is viewed through a large glass skylight set flush with the cobbles of the square. Interesting and thought provoking!
