Water tower Norderney, Water tower and architectural heritage monument in Norderney, Germany

The Water Tower Norderney is a 46.2-metre square brick tower with eleven-metre sides, completed in 1929 and topped by a viewing platform above a 500,000-litre tank. Its facade carries protruding clinker ornaments: fish on the north side, seabirds on the east, the Norderney cape with the copper date 1929 on the south, and Neptune rising from the water on the west.

Construction took place between 1929 and 1930 in response to growing water demands from the expanding island population and tourism industry. The project represented a major shift in how the island managed its water supply infrastructure.

The tower's brick facade carries protruding clinker ornaments on each side: fish leaping from water on the north, seabirds over water on the east, the Norderney Kap with the copper date 1929 on the south, and Neptune or Poseidon rising from the water on the west. The design was modelled on the church tower of Marienhafe.

The tower itself is closed to the public because a working water extraction plant occupies the lower level. Guided tours to the viewing platform above the tank run between April and October; 205 steps lead to the top. A webcam is mounted on the tower.

The viewing platform sits above the 500,000-litre tank, reached by 205 steps; tours run between April and October. At night the tower is lit with changing LED colours, and its webcam looks out over the island. On clear nights the beam of the Helgoland lighthouse, about 71 kilometres away, can be made out from the top.
