Old Water Tower, Water tower and cultural monument in Tábor, Czech Republic.

The Old Water Tower is a three-storey Renaissance tower with a rectangular plan, attached to Tábor's medieval fortification wall. Its facades are covered in psaníčko sgraffito, and both the north and south fronts end in arched gables. A narrow wooden door on the west side opens onto a steep wooden staircase serving the floors.

The Old Water Tower was built in 1502, after the Jordán reservoir was completed, to supply Tábor with drinking and utility water. Water was pumped from the reservoir, 32 metres below, by equipment driven by water mills and distributed through wooden pipes to the town's fountains. After the great fire of 1559 the tower was rebuilt and given two Renaissance arched gables. The reservoir was replaced in 1874, and the tower was repaired in 1877 and 1925.

The tower sits at the heart of Tábor's evolution and shows how the city pushed forward with technical progress. Visitors can see today how earlier generations brought water to the city and changed daily life in the process.

The tower stands at the northern end of Žižkova ulice, at the southern edge of Tržní náměstí, next to the late Gothic town hall on Žižkovo náměstí. Entry is through a narrow wooden door on the west side; inside, the floors are connected by a narrow, fairly steep wooden staircase. The gallery in the tower has been run by the city of Tábor since 1997.

The tower has housed the city-run Vodárenská věž gallery since 1997, showing mainly young and emerging artists in its unusual interior spaces. The narrow, fairly steep wooden staircase and the wooden floor structures between floors are part of the visit.
