At 232 meters, the Mont des Alouettes is one of the highest peaks in the Vendée and has an exceptional panorama.
At the time, 8 windmills were established there. Today there are 2 left, one of which is still in working order.
During the Vendée War, the peasants used the mills to communicate with each other. The millers sent messages from hill to hill, orienting the wings of the mills, according to a code with four types of messages: near danger, past danger, gathering (cross wings) and rest (St Andre's cross). This use earned them massive destruction by the Republicans led by Turreau, in October 1793.
