The small village of Delettes includes the hamlets of Upen d'Amont, Upen d'Aval, and Westrehem. Crossed by the Lys River, it boasts a pretty sluice mill built on the banks of the river.

This Spanish mill was built around 1635, on the banks of the Lacquette River. It produced flour until 1938, then milling for livestock. It was bought in 1974 to be transformed into a home. It is built with brick and stone (white limestone). All that remains of the original building is the north gable (17th century), and also a porch. The water wheel is still in place but it no longer turns. The dam forms a pretty waterfall. A turret was added on the river side. It is a very beautiful private home with a beautiful garden in which you can see a stone fountain.
