This is the former chapel (end of the 17th century) of the Collège Sainte-Marie. The facade is in Jesuit style. The rich decoration follows the Flemish tradition: ringed columns and pillars, broken pediments and curled, inverted consoles.

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.
