Like a ship made of glass and metal, the chocolate museum is located in the Rheinau harbour, directly in front of the old town, near the Cologne Cathedral. In medieval times in Cologne, the anchor and terminal were located here by the Rhine boatmen. Today the old swing bridge has been renovated to the new designed harbour quarter of the "Rheinauhafen". The tour of the nine exhibition areas is a fantastic and unforgettable journey through the 4000 square metre of the culture and history of chocolate, starting at the old American cultures such as the Maya and the Aztecs, through the Baroque age and the industrialisation up to the individual refinement of the noble chocolate of today.
