Castle Ritzebüttel, Cuxhaven, Lower Saxony

The mighty tower in the back is from the early 14th century, the baroque addition at the front from the 18th century.

For centuries, the tower near the Elbe estuary was owned by the city of Hamburg, which used it as an outpost against pirates who threatened the operations of the port of Hamburg. Later, it was the residence and office of the Hamburg Governor of Cuxhaven.

Cuxhaven is now Germany’s largest seaside spa town, and Ritzebüttel is a museum of local history.
