Brežice Water Tower, Water tower in Brežice, Slovenia.

Brežice Water Tower is a 46-metre cylindrical brick tower with an octagonal tank chamber at the top, covered by an eight-sided pyramidal roof. The reinforced-concrete tank inside is 6 metres high and 6 metres wide, holding 203 m³. Since its 2022 renovation it houses a museum of water infrastructure and an observation tower.

This tower was built in 1914 when the city constructed a new sewage system. It served as the main water storage for the city for many years until another facility eventually took over its role.

The tower shows how people in this town managed their water supply and what advances they made over time. The displays help visitors understand the role that clean water played in daily city life.

An elevator serves the tower, and three small balconies at a height of 19.84 m hold mounted telescopes for looking out over Brežice. The tower stands in the town centre, and since the 2022 renovation it is run by the Posavje Museum Brežice as a branch museum and viewing tower.

The tower is one of only two surviving water towers of its kind in Slovenia, alongside the Kranj Water Tower built in 1911. Its tank was a cylindrical reinforced-concrete vessel 6 metres high and 6 metres wide, holding 203 m³ of water. The tower withstood the strong earthquake that struck Brežice on 29 January 1917, just over two years after it was built.
