The Germanisches Nationalmuseum is home to one of the most important collections of German culture and art from early history to the present, containing over 1.3 million objects. The museum was founded already in 1852, just after the political unification of the German states had failed. It was intended to document the culture of German-speaking peoples across all borders. The museum is housed in a building complex around the late medieval Carthusian Monastery, which was supplemented after World War II and extended in 1996 for 72 million Euro. The collections include the pre-and early history collection with the famous Gold Hat, paintings including works of Albrecht Dürer, arts and crafts of the Middle Ages and modern times, clothing, home decor, historic musical instruments and a library of over 650,000 volumes. In the era of National Socialism, the museum's management avoided to become the point of identification for the ideology, so it never came to a visit by Adolf Hitler.
