Wasserturm

The Water Tower is a well-known landmark of Mannheim, Germany. The water tower was built from 1886 to 1889 on the present Frederick Square by Gustav Halmhuber. The tower, which is 60 meters high and 19 meters in diameter, was Mannheim's first urban water tower. It initially had to meet with the required standards as a drinking water supply while maintaining steady water pressure. After the construction of the higher Luzenberg water tower in 1909, the Mannheim water tower served as an aboveground water tank until 2000.
