"Parthenon of Books," as the work is known, was built by Argentinean artist Marta Minujín. The books used to construct the piece are copies of those works the Nazi regime either declared verboten or burned.
Just as the structure itself is fascinating, so too is its location; it is the same spot where the Nazis burned books written by Jews and Marxists in May 1933.
The exhibition, which opened last week as part of the "Documenta" festival in the city, will stand for 100 days and is intended to be an act of protest against censorship, the persecution of writers, the prohibition of distributing texts for political reasons, discrimination, violence and intolerance.
