The Empty Library, a Memorial in memory of the burning of books by Micha Ullman consisting of a glass plate set into the cobblestones, gives a view of a group of empty bookcases large enough to hold all 20,000 burned books; its purpose is to commemorate the book burning. Furthermore, a line of Heinrich Heine from his play, Almansor (1821), is engraved on a plaque inset in the square: "Das war ein Vorspiel nur, dort wo man Bücher verbrennt, verbrennt man am Ende auch Menschen."
