Watermill in Poteplí, Watermill and cultural monument in Poteplí, Czech Republic.

Proškův mlýn stands in the middle of Poteplí, part of Malé Kyšice, beside the Kačák stream. The mill building is accompanied by a former inn, now the restaurant U Netopýra, and a gamekeeper's lodge. The site has been a listed cultural monument since 17 December 1987.

The mill is first documented in 1548, when Vladislav Bezdruický z Kolovrat inherited "Mlýn pod Teplým". It burned during the Thirty Years' War and was rebuilt by miller Kašpar Votava. In 1892 Anna Konvalinková sold it to Josef Prošek, whose name it bears; it operated until the start of World War II and was listed as a cultural monument on 17 December 1987.

The mill shows how water was once used to power daily work and what role such places held in village life. People came here to have their grain ground, and the miller was an important figure in the community.

The mill stands in the middle of Poteplí, a hamlet of Malé Kyšice, with the Kačák stream flowing through the village. A bus or car from Prague takes about an hour or 30 minutes respectively. The former swimming pool nearby has not operated since the early 21st century, and a large cottage settlement lines the stream.

The building preserves original mechanical parts that show how water specifically powered the grinding stones and what simple but effective constructions were used. These visible details allow visitors to understand the craftsmanship needed to build and maintain such systems.
