The Johanna mill is a working corn mill located on Prijsseweg in the town of Culemborg. The mill was built in 1878 by the brothers Jan and Pieter de Heus. It is a wooden mill with a stone base. In 1888 the mill was almost totally destroyed in a fire. The mill was rebuilt in the same year. In 1921 the mill was purchased by the Schennink family, who still own the mill today. Restoration work was carried out in 1942, 1954, and 1974. The mill is open to the public, with tours available by appointment.
