The Eva Mill in Usquert was built in 1891 by the mill-maker Chr. Bremer of Middelstum, following a commission by the landowner K. E. Welt. In 1953, the mill was bought by the municipality of Usquert. The Eva mill was restored in 2001, and is still in use as a corn mill today. The mill is open to the public, and regular guided tours are available. The mill foundation often organizes nature walks, bike rides, and other events for tourists to enjoy.
