Guennoc island

Guennoc Island is a small islet off the Breton coast with four stone burial chambers aligned along its central ridge. It stretches roughly 400 meters in length and features steep cliff faces at its edges.

The earliest burial structures on the island date to the Stone Age and rank among Europe's oldest monuments. Later inhabitants including Gallic peoples also left their mark, showing continuous use of the place over thousands of years.

The four megalithic cairns scattered across the island served as burial chambers and remain central to how people understand this place. These ancient burial sites connect visitors to the communities that lived here thousands of years ago.

A visit depends on tide conditions and requires advance permission and planning. Always check local information about access times and take water safety seriously when traveling to and around the island.

The island displays remains of Gallic settlements with fortifications and farm traces on its eastern slopes. These often overlooked details reveal how different peoples lived side by side and shaped the landscape.
