Sternschanzenpark, Urban park in Sternschanze, Hamburg, Germany

Sternschanzenpark is a roughly twelve-hectare park in Hamburg's Sternschanze quarter, in the Altona district, on a 28-metre hill. Its landmark is the Schanzenturm, a 57.5-metre octagonal former water tower with a diameter of 32 metres, built 1907–1910 and now a hotel. The grounds hold lawns, playgrounds, boule courts, football pitches and the stadium of the police sports club.

The site was built in 1866 as a military fortification, which is why the park's name includes the word Schanze, the German word for a defensive earthwork. When the military use ended, the city converted the land into a public green space for residents.

The park sits at the edge of the Schanzenviertel, a neighborhood known for its alternative scene and street art. On warm days, the lawn fills with people playing music, sharing food, and spending time together in an informal way.

The park is open from multiple sides and easy to reach on foot or by bike from the surrounding streets. Some of the paths on the hillside can get muddy after rain, so wearing sturdy footwear on wet days is a good idea.

The red brick water tower rising above the park's hill was once among the largest in Europe and now operates as a hotel. Guests sleep inside the former tank structure, which still dominates the skyline when viewed from the lower part of the park.
