Hundreds of Jewish children were hidden in the town of Castelnau-le-Lez during the
Holocaust. Almost every home hid children, in some cases from multiple families. After the war, the children whose parents had survived were returned to them. The people of the town and the local priest were well aware of the situation and, at least tacitly, supported it. The
Hôtel de Ville was completed in 1972. ==Twin towns==
