The tall monument dedicated to Johannes Gutenberg, the inventor of the printing press, depicts him and his two patrons. It was installed here on the occasion of the celebration of the 400th anniversary of the invention of the printing press. The historical nature of the statue contrasts interestingly with the surrounding skyscrapers.
