Île du Pilier

Île du Pilier is a small rocky island several kilometers northwest of Noirmoutier, separated from the main island by a shipping channel. The site spans about 4 hectares and is marked by two lighthouses, one operating automatically and one from historical times, as well as a restored former semaphore building.

The island was inhabited in prehistoric times, as evidenced by Neolithic archaeological finds. In the Middle Ages, Cistercian monks established a small community here in 1172 but abandoned the site after about 30 years, and later the island was developed as a defensive position.

The island today serves mainly as a refuge for seabirds that nest and breed here. The bare rocks and sparse vegetation shape the appearance of a place that belongs entirely to wild nature and is only observed by visitors.

The island is only accessible by boat and visits are restricted during nesting season between April and June to avoid disturbing breeding birds. Visitors should note that weather and tidal conditions can change conditions there and should check ahead.

The name may come from an old word meaning 'island of girls' but historians do not confirm this legend. Regardless, the unclear origin of the name adds to the impression that this small island keeps its secrets from the past.
