Unusual Hotels in Schleswig Holstein

Hotel im Wasserturm (formerly Wasserturm Hotel Cologne) occupies a towering 19th-century water tower, once Europe’s largest, now transformed into a dramatic boutique stay. Its cylindrical brick façade and vaulted lobby retain the original Romanesque charm, while 88 individually designed rooms and suites curve around the tower’s circular shape. A glass-walled rooftop restaurant and bar crown the tower, offering panoramic city views and a leafy conservatory feel. The result is a masterful blend of industrial heritage, architectural boldness, and luxury: staying here means sleeping inside a piece of city history.
