In Kassel, Germany, at the very site where Nazis once burned over 2,000 books by Jewish and Marxist writers, one artist has built a colossal tribute to free speech. The “Parthenon of Books” is a giant temporary replica of the famous Greek temple in Athens. The installation is covered by more than 100,000 books that have been banned at various stages throughout history. Created by Argentine artist Marta Minujín, the exhibit is meant to spark debate over censorship in literature. Once the exhibition is over, these books will be handed out to allow the banned to enter literary circulation once more.
