Chocolate Museum, Cologne

Opened in 1993, the Chocolate Museum is located in Cologne's former harbor, and the building has been designed in the shape of a ship's prow in deference to this maritime connection. Architect Ernst Eller constructed the building almost entirely out of glass, according to the specifications of Hans Imhoff, head of the Stollwerck company. The firm has also influenced the name of the museum, which in full reads 'The Imhoff-Stollwerck Museum of the Past and Present of Chocolate'. Visitors can drink from the warm chocolate spring and try out the home-made chocolate produced in the factory.
