Wasserturm Westend, Water tower in Charlottenburg, Germany.

Wasserturm Westend consists of two former water towers, Charlottenburg I and II, on Akazienallee and Spandauer Damm in Berlin's Westend. The smaller east tower dates from 1881; the taller tower, 60 metres high, was built in 1909–1910. A house in Dutch style stands between them, and all three belong to the protected ensemble.

Construction began in 1909 under architect Heinrich Seeling's direction to meet Berlin's growing water needs. The project was part of a major infrastructure effort to supply a rapidly expanding city.

The tower emerged during a period when Berlin was reshaping its infrastructure, creating architectural styles that remain visible throughout the city today. The red brick facade and clear geometric form show how engineers of that era blended practical function with visual design.

The tower sits at a busy street corner and is easy to reach when exploring the Charlottenburg area. As a protected monument, it can be viewed from the outside, and taking a short walk through the surrounding streets offers the best views of the structure.

The two towers differ in size: Charlottenburg II rises 60 metres with a diameter of 16 metres, while the older eastern tower is smaller, at 14 metres across. Since 2012 an annex with lift and staircase connects them, and the taller tower holds twelve flats on 14 floors, the smaller seven lofts on seven floors.
