Moulin des Invalides

Highlight • Other

The Moulin des Invalides is a watermill on the Laquette, located in the city of Aire-sur-la-Lys, part of the French department of Pas-de-Calais. The mill functioned as a flour mill. The mill was built in 1682 for Count De Robelin, who was an engineer for the French king. The builders were soldiers who were no longer fit for military service due to their injuries. In 1790 it was reported that the mill had two paddle wheels, but the current was too weak to turn both wheels. In 1840 the mill was partly rebuilt and enlarged. A winch was also installed to hoist the bags of grain. Mechanization followed in the course of the 19th century and the current building was erected in 1878. Electric propulsion arrived in the 20th century. In 1979 the company was closed down. In 1996 a new water wheel was installed, which had the same diameter of 5.2 meters as in 1790.

Chapelle Beaudelle

Highlight • Other

The chapel was built in 1877 thanks to a donation from Jean-Baptiste Beaudelle, a wealthy resident of the town. He wanted to build a chapel for the hospice of Aire-sur-la-Lys, and so the Chapelle Beaudelle was born. The building is designed in a neo-Gothic style, which was a popular architectural movement at the time.

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.

Hazebrouck

Highlight • Settlement

Hazebrouck invites you to stroll between its lively Grand Place and its pedestrian street lined with shops.
