Kolin water tower, Water tower in Kolín, Czech Republic

The Kolín water tower is a 45-metre reinforced-concrete tower on a slight hill on Míru Street in the Pražské Předměstí district. Architect František Janda added a viewing gallery at 36 metres, supported by concrete columns, with a stairway leading up to it.

The original Štítarský water supply was built between 1896 and 1904 to Jan Hráský's design. Its 1928–1930 expansion added two wells 28 and 35 m deep by the Štítarský stream, a pumping station, and this 45 m tower holding 450 m³, built by Hráský and architect František Janda. Pumping stopped in 1977; the city bought the tower in 2005 and reopened it in 2015.

The tower's name, Vodárna, comes from its role supplying water to nearly all of Kolín except Zálabí and a few streets of the Kutnohorská suburb. Since 2015 visitors climb almost 300 steps to a viewing gallery at 36 m, where a video projection in the former tank presents the building's history and water supply.

The tower stands on a slight rise on Míru Street in the Pražské předměstí district, in the western part of Kolín, not by the railway station. About 300 steps lead up to the viewing gallery at 36 m; no lift was permitted, so the climb is on foot.

The tower's viewing gallery at 36 metres was designed by architect František Janda, who added a stairway, a small resting alcove and a fountain beneath the concrete columns. A lift was proposed during the 2015 conversion but heritage officials refused permission, so visitors climb almost 300 steps.
