Megaliths and moors of Saint Just

North of Redon, this site is known for its megalithic monuments which cover nearly 6 kilometres. It is a veritable sanctuary offering visitors protected natural treasures. Go back in time as you stroll!


The site of the megaliths and moors of Saint‑Just is a natural area formed of rocks that are over 470 million years old, among which broom and gorse grow. The wild landscapes are home to a rich and varied fauna and flora.

This protected area contains a diversity of megaliths that are unique in Europe, erected in the Neolithic period, between 5 000 and 2 000 BCE : alignments, enclosures, mounds, tumulus, cairns, corridor dolmen, etc.

Considered the second megalithic site in Brittany after Carnac, it contains a vast sacred space that was used for over 3,000 years.



The site contains different places suitable for visitors of all ages:

  • A permanent exhibition dedicated to megalithic art is presented at Maison Mégalithes et Landes. Visitors are immersed in the Neolithic period, megalithic art and the main digs carried out on the Saint-Just site. Guided tours, pre-historic workshops and an initiation into archaeology are also proposed.
  • One of the loveliest walks in Ille-et-Vilaine, a new interpretation trail provides a great way to discover and admire the beauty of the Breton moors in 3 loops lasting from 1 hour to 2 and a half hours.
  • Three geocaching trails, life-size treasure hunts allow children and parents to learn while having fun.
  • Climbing enthusiasts can also clamber on the rocks that overlook Etang du Val, which offer many opportunities to practice.

Seeing these alignments of standing stones and covered alleys and thinking that the site was populated 7,000 years ago… that’s impressive!
