Île Milliau

Île Milliau is a tidal island of about 23 hectares off the coast of Trébeurden in Brittany, stretching roughly one kilometer in length. It features varied terrain with moorland, ferns, and maritime shrubs, crossed by old pathways that become accessible at low tide.

The island contains Ty Liac'h, a Neolithic stone gallery grave made of ten standing stones and three horizontal slabs. This monument dates to a time when people already lived along this coast and built burial structures in this location.

The island takes its name from Saint Miliau, a religious figure who settled here in the sixth century and left a lasting mark on the region. His legacy remains woven into the local names and stories that travelers hear about the area.

To visit the island, you must plan around tide schedules since it is only accessible on foot at low tide. Marked pathways connect to the mainland, but it is essential to check the timing windows before heading out to avoid being cut off by returning water.

In the early 1900s, Lucie Jourdan built Villa Aristide Briand on the island as a private residence. The building remained her home until German occupation during World War II, serving as a reminder of a peaceful era before the coast became touched by wartime events.
