Water tower Ratzeburg Hindenburghöhe, Water tower at Hindenburghöhe, Ratzeburg, Germany.

The Water tower Ratzeburg Hindenburghöhe is an octagonal, brick-clad reinforced-concrete structure built in 1935 around an older square tower. Four octagonal storeys rise to an observation platform with wide wall openings, topped by a cylindrical water tank. Long vertical window rows set the upper section apart from the base.

The first water and observation tower on Hindenburghöhe was built in 1902/03 as part of Emil Palmer's central water supply, with a square neo-Romanesque design and a 30 m³ tank. In 1934/35 an octagonal brick-clad reinforced concrete skeleton was built around it to support a 260 m³ tank, allowing the networks of St. Georgsberg and Hindenburghöhe to merge. The tower was decommissioned in 1976 and has stood empty since the 1990s.

The tower's name refers to the Hindenburghöhe, the wooded rise east of the old town that served as a viewpoint before the tower was built. The 1903 structure was designed in the neo-Romanesque style then popular; the 1935 brick-clad concrete shell surrounds the old tower, which survives intact inside. Since 1988 the building has been a listed monument.

The tower sits in a wooded area east of Ratzeburg's old town and is accessible by foot from the town center. The building remains closed to visitors due to storm damage and restoration needs that have not yet been addressed.

The 1903 tower still stands inside the 1935 shell: the octagonal brick-clad concrete frame was built around the old square neo-Romanesque structure, which remains complete within. The new tank held 260 m³, against the original 30 m³.
