The Mannheim Water Tower is a historic water tower located in Mannheim, Germany. It was built in 1889 in the Art Nouveau style and is now considered a symbol of the city. The tower was designed by Gustav Halmhuber and was originally built to supply Mannheim with water from the River Rhine.

The tower stands at a height of 60 meters and has a water capacity of 1,200 cubic meters. The water was pumped from the river using steam engines, and then stored in the tower before being distributed to the city via a network of pipes.

Today, the Mannheim Water Tower is no longer used as a water supply system, but rather serves as a cultural and event venue. It has been extensively renovated and restored over the years, and now features a restaurant, a museum, and a gallery. The tower offers panoramic views of Mannheim and the surrounding area from its observation deck, which is accessible by elevator. The tower is also illuminated at night, making it a popular landmark in the city.
