Ever since the printing-press was invented, different regimes have tried to censor books they found controversial. In fact, Argentinian artist Marta Minujín worked with researchers from the University of Kassel to identify over 72,000 forbidden titles going back to the early 1500s. As a massive physical monument to the history of attempted censorship, Minujín is building a “Parthenon of Books” using every banned title that they can identify, including books like Alice’s Adventures in Wonderland and 1984. When it’s all finished, the project will be built with up to 100,000 books.
