Water tower of Siófok, Water tower and tourist center in Siófok, Hungary.

The Water tower of Siófok is a reinforced-concrete tower on Fő tér, built in 1911–12 to designs by Jenő Gergely and Árpád Gut. Its height is given as 41.30 m by recent measurements, against 45 m in older descriptions. A five-metre-high tank holding 250 m³ once sat at the top; the 2010s renovation added two panoramic lifts, large glass fronts and a 360° open viewing level.

The structure was built in 1912 and supplied water to the city for many decades. During World War II, German forces used the building, and it eventually ceased functioning as a water supply facility.

The tower displays exhibitions about Siófok's development and Lake Balaton through interactive elements and games. Visitors can learn about local history in an engaging way.

Glass elevators make reaching the top easy and accessible, with viewing levels at different heights offering varied perspectives. The upper levels are best visited in clear weather for optimal visibility.

The tower is the northern endpoint of the Dél-dunántúli Pirostúra, a red-marked hiking trail more than 320 km long. The permanent exhibition on Varga Imre, Siófok's first honorary citizen, was assembled by his son, sculptor Tamás Varga, who donated the plaster sculptures and personal objects.
