The Rosmolen is a classical 17th century water mill located on De Rosmolen in the town of Geysteren. The mill was built in 1677, and takes its name from the farm which it originally served. The mill was decommissioned in 1928, and bought by the town shortly afterwards. The Rosmolen suffered heavy damage during World War Two, when German forces blew up a nearby bridge. The damage was repaired in the 1970s. Tours of The Rosmolen are available by appointment only.
