Den Leeuw Meulen (also: Moulin du Lion) is a windmill in the municipality of Pitgam in the French Northern Department. This post mill functioned as a flour mill. The mill was built in 1774, according to an inscription in the mill spindle. The owner at the time was Guillaume Delabaere, and the mill remained in this family until 1923. The mill had three pairs of millstones. In 1923 the mill was sold to Lucien Dendrael, who remained the owner until his death in 1946. Until this year the mill was in operation, partly by millers who rented it from the owner. After this the mill fell into disrepair. However, in 1970 it was classified as a village view. However, the stand was in poor condition and in the autumn of 1983 the mill house fell to the ground.
The miller's heirs sold the mill to the municipality in 1984. With the help of the mayor, the mill was restored and in 1989 it was operational again.
