The Lana Mariana is an historic corn mill in the town of Harskamp. It is a round stone beltmill, and was used for grinding corn. The mill was built in 1739. In 1945 the mill was damaged by Canadian troops, and for several decades the mill had a bare hull. In 1983 the mill was bought by G. de Geit, and in 1985 the mill was restored, but the new hood was not different to the original design. The interior of the mill was intended to be used as a private residence, and is now used as a function hall and restaurant.
