Les Causeurs

Les Causeurs consists of two upright granite blocks standing near the island's church at Place François le Sud, reaching heights of 2.30 and 2.80 meters. These stones form the main features of a Neolithic archaeological site.

These stones date from the Neolithic period and represent evidence of early human settlement on the island. They were officially designated as protected heritage monuments in 1901 and form part of a broader complex of prehistoric occupation sites discovered in the 1870s.

The stones have a profile resembling two figures in conversation, which inspired their Breton name 'Ar Fillistérien', meaning 'The Chatters'. This connection to dialogue and interaction gives these monuments a distinctive place in local identity.

The site sits in the center of the island and is easily accessible on foot from the harbor. Since the location is open and unobstructed, visitors can explore it freely throughout the day.

Local tradition held that placing nine pebbles wrapped in cloth at the base of the stones could cure fever. This practice reveals how the site was intertwined with folk healing beliefs in the community.
