The Leumolen or Sint-Ursulamolen is a watermill on the Leubeek, near Nunhem, in the Dutch municipality of Leudal. This functions as a flour mill and oil mill. This is an undershot mill.
The mill was first mentioned in 1461, although there is already a mention of a mill in Nunhem from 1276, but it is not certain whether it was the same mill.
The mill and the associated farm Leuhof were a fief of the County of Horn (the feudal lord). In 1701, the Sint-Elisabethsdal Monastery acquired the property through purchase, but it remained a fief of the Counts of Horn. In 1773, a stone mill was built to replace the dilapidated predecessor, which was half-timbered. The year "1773" is still present in an anchor. The flour mill was also expanded with an oil mill. The roof was crowned with a turret.
In 1796, the mill and courtyard were seized by the French and sold to private individuals. In 1822 it came into the possession of the Waegemans family, who lived at Nunhem Castle. This family leased the mill. In 1828 a request was made to expand the mill with a peeling mill. In the early 20th century, the wooden water wheel was replaced by a Girard turbine.
In 1935 the last heiress sold the Leumolen to another private individual and it was sold to the State in 1956. The mill is managed by Staatsbosbeheer.
The mill was in operation until the 1950s, after which it was closed down. It was restored in 1961 and was once again operational as a flour mill. A new wooden water wheel was installed. In 2008, the oil mill was also restored and oil could be minted again.
