The Salaire Bridge on Île d'Olonne in Vendée was built in 1758 by Lord Julien Gallouin to replace a ferry that had become inadequate and dangerous, facilitating passage to the region's salt marshes. This wooden bridge, supported by cut stone pillars, replaced a paid ferry service used by farmers and salt workers for several centuries. Over the years, the bridge suffered from a state of disrepair, which a property owners' association helped to preserve in the late 19th century, before a major reconstruction was completed in 1935. Further renovations took place in 1980, followed by a complete reconstruction in 2018, which preserved its historic appearance by reusing the original materials.

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.
