Once Europe's tallest water tower at 117 feet, this luxury spherical hotel quenched Cologne's thirst from 1872 to the late 1890s. Since opening in 1990, the 78-room Hotel im Wasserturm has cloistered weary travelers and movie stars (including Catherine Deneuve and Brad Pitt). After restoring the tower's exterior walls (damaged in World War II), the architects divided the building into 11 floors.
