Vodní mlýn s pilou, Watermill in Trhonice, Czech Republic.

Vodní mlýn s pilou is a four-winged mill complex around a closed courtyard south of Trhonice, consisting of a timbered mill building with attached dwelling and a separate single-blade saw. The saw's lower part is stone, its upper part boarded and partly open, under a gabled roof with a break. The mill race led water from a weir to two upper-shot water wheels recorded in 1930.

The mill is first documented in the mid-16th century, when it was a wooden structure with a single waterwheel. It burned down after the Thirty Years' War and stood abandoned. In the 18th century the miller added a single-blade saw and a linseed-oil press; the building was partly rebuilt in masonry in 1843, and a diesel engine was installed in 1908. Milling ceased on 23 November 1941, according to Filip's inventory of mills.

The mill's Czech name, Vodní mlýn s pilou a olejnou, names its three trades: grain milling, one-blade sawing and flax-oil pressing. The oil press with its machine-driven press survives complete, and the site also generated electricity and drove farm machinery.

The building is located in Trhonice and easy to reach, with parking spots nearby. Wear comfortable shoes since the ground around the mill may be uneven or wet from the water flow.

The mill operated with two different functions at once, grinding grain and sawing wood powered by the same water flow. This dual system made it especially useful for the time period.
