Guilliguy Megaliths

Highlight • Other

The Guilliguy site is home to megaliths around 8,000 years old. Listed as a historic monument since 1921, there is a covered walkway, a menhir and a cross. The view over Portsall Bay is pleasant.

Facing the vastness of the sea, the Saint-Samson chapel makes us feel infinitely small. It is no wonder that the site has been a place of worship since prehistoric times. The chapel itself was built in the 17th century.
