Many centuries ago, our ancestors discovered the possibility of harnessing the power of the elements—which, on the one hand, were helpful and useful, but on the other hand, as untamed forces of nature, could also be a threat—for various purposes, thus eliminating the need for human or animal muscle power. Mills such as these are a good example of the human engineering skills of earlier generations: The heavy millstones used to grind grain or press oil, for example, could be powered by wind or—as in this case—water.

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.

The Ascenseur à bateaux des Fontinettes is a historic boat lift in Arques, France. It was built between 1881 and 1887 and is the only remaining boat lift in France. It was built to connect the Lys River with the Aa, thus giving Lille and other inland cities a French route to the sea. The canal has a maximum height of 19 meters and a minimum height of 3 meters. It is a unique example of hydraulic engineering and works according to the principle of the vessels of Communicating and Archimedes' law. It can carry two boats at the same time and it takes about 22 minutes to raise or lower a boat. It is a popular tourist attraction and offers a fascinating insight into France's industrial history.

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)
