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.

This is one of the finest examples of the Flamboyant Gothic and Renaissance in French Flanders. The imposing tower (62m) resembles that of Notre-Dame in Saint-Omer. Inside, the pattern of the ribs of the vaults has been transferred to the floor. The choir is closed by a beautiful rood screen; on the left is the gilded statue of Notre-Dame Panetière. The oak organ case comes from the abbey church of Clamarais. Choir and apse suffered from a bombardment in 1944. In the back you can see a beautiful Virgin and Child (15th century)
