The New Harbour in Bremerhaven is protected by a dike. Behind the dike lie the German Maritime Museum, the Klimahaus and further behind the city’s center. Right behind the dike stands a sculpture to commemorate the danger of storm surges. Copper rings on the pole of the sculpture show the maximum water levels of past storm surges (1717, 1825, 1906, 1936, 1962, 1973). On the top is a copper model of the Bremen Hanseatic Cog over a globe that can be rotated in the wind. The model was created by the Bremerhaven sculptor Gerhard Olbrich in 1975 and can be seen from both sides of the dike.
