Hamerský mlýn, former blacksmith's workshop and waterworks in Kanice, Czech Republic

Hamerský mlýn is a historic watermill located on the Svitava River in Kanice near Brno. The structure features a large water wheel and industrial-era architectural elements that remain visible today.

The first record of a building here dates from 1820 and describes a blacksmith's workshop about five by twelve metres with a pitched roof facing the river. Around 1900 Julius Kovář bought the workshop and set up a small factory making gears, powered by a Zuppinger wheel he designed himself. Gear and file production continued into the 1920s under Václav Kovář; in 1938 a flood hit the valley and the workshops were sold to Anna and Emil Pohl, who ran a tannery there until 1948.

The name Kovářovo údolí (Smith's Valley) comes from the Kovář family, who ran a file-making workshop here; locals called the buildings the pilníkárna (file works). Since 2010 the site has hosted Obřanský obr, an annual gathering of artistic blacksmiths and craftspeople demonstrating their trades. Kovář's granddaughter Dagmar Kartousová has attended and described her grandparents selling beer and tvarůžky in the workshop's pub.

The complex stands on the Svitava, on the Kanice bank of the river, about 5 km north of central Brno, right beside the cycle path linking Obřany and Bílovice nad Svitavou. The buildings have been under reconstruction since 2007 and are not a finished museum, so expect a working site rather than a visitor facility.

The mill uses an Ewart chain system for power transmission, with water driving the wheel from below in a specialized mechanical arrangement. This technical feature shows the innovation that characterized industrial facilities around 1900.
