The Gueffard Mill on Île d'Olonne is an old windmill dating back to at least the 17th century, mentioned in 1656 under the name "moulin du Bourg". It was a common mill belonging to the lord of the Court of Île d'Olonne, who earned an income from its operation. This mill operated until 1932, with a diameter of 5.4 meters and a height of over 7 meters, equipped with a system allowing its sails to be oriented according to the wind. After years of abandonment, it was purchased by the municipality in 2002, and an association began its restoration in 2016, including the consolidation of the foundations and the creation of a belvedere. The mill is an important historical symbol of the local heritage of Île d'Olonne.

Be careful, the track is not paved and not necessarily very wide in places. Otherwise, it's a real pain :-)
