Hamburg's Speicherstadt The Speicherstadt Hamburg is one of the most popular sights of Hamburg and can be reached with the U3 line within 27 minutes. The largest contiguous warehouse complex in the world was declared as World Heritage Site in 2015 and was built as early as 1883 as a section of the Port of Hamburg.Even today, the scent of the great wide world seems to float above the old warehouses. Built on ancient oak piles, the six- to seven-storeyed brick buildings once served as duty-free storage areas for coffee, cocoa, tobacco, tea and high-quality general cargo. They represent the largest contiguous warehouse complex in the world. The old Speicherstadt can be easily explored both by land and by water. Let yourself be enchanted by this over hundred year old district and get to know one of Hamburg's most popular tourist destinations!
