Mégalithes du Guilliguy

Mégalithes du Guilliguy is a Neolithic site in Brittany with an upright stone made of granite and an underground burial chamber connected by a corridor. The chamber is formed by stone slabs and features a side entrance that was originally sealed with a carefully fitted stone.

This burial site was built roughly 5000 years ago during the Neolithic period, as scientific analysis shows. It belongs to a family of megalithic structures that were constructed over thousands of years across western Europe.

The name Guilliguy reflects the Breton landscape where this site stands, and it reveals how Neolithic people used underground chambers to honor their dead. The way the passage and burial room are arranged shows the care these early communities took in creating lasting spaces for their rituals.

The site is reachable via a walking path that starts from the nearby port area and crosses through local countryside. Sturdy shoes are recommended since the ground can be uneven and the surroundings are exposed to the weather year-round.

The underground chamber has a tiny circular side entrance that was sealed with a stone disc fitting so precisely it lasted thousands of years. This shows the builders possessed remarkable craftsmanship and paid great attention to detail in their work.
