Wasserturm Eutin, Water tower and cultural heritage monument in Eutin, Germany.

Wasserturm Eutin is a 39.2-metre round brick tower on a polygonal base, built in 1909 at the town's highest point. Pointed-arch windows and portal, green-glazed tiles at the transition to the narrower conical shaft, and a copper-clad conical roof. A crenellated parapet rings the widened tank section, and blind niches articulate the brickwork.

The tower was built in 1909 at the highest point of Eutin, following a devastating fire on 19 January 1907 that showed the need for pressurised mains water. At the same time the waterworks was built on the Deefstieg. The tower remained in service until it was taken off the network in 2006.

The tower's neo-Gothic detailing recalls Brick Gothic: a crenellated parapet rings the widened tank storey, and blind niches, some plastered, pattern the brickwork. The conical roof was originally covered in tin, later replaced with copper. Since 2006 the tower has hosted contemporary art exhibitions on three gallery floors, plus a permanent photo display of every water tower in Schleswig-Holstein.

The tower opens to visitors only in the summer months; the sources give no fixed dates, so confirm current opening days before climbing. The spiral staircase runs inside a tube through the water tank itself, and 156 steps lead to the walkway between the roof and the battlemented parapet. The galleries on three floors are reached from the same stair.

The spiral staircase to the viewing platform runs inside a cylinder that pierces the riveted Intze 1 tank holding 250 m³ of water. Three floors of galleries host temporary contemporary art exhibitions, and a permanent photo display shows every water tower in Schleswig-Holstein.
