Dolmen des Îles, Prehistoric burial site in Voutré, France.

The Dolmen des Îles is a ruined dolmen at the lieu-dit Béziet in a field at Voutré, Mayenne. Its stones lie scattered rather than forming a standing chamber, and the site is on private land. It was listed as a monument historique in 1978.

The structure dates from the Neolithic period and ranks among the oldest monumental constructions in the Mayenne region. It was officially designated as a protected historical monument in 1978, marking its recognition as an important archaeological site.

The name "des Îles" refers to the hamlet of Les Îles, and the monument stands at a spot called Béziet in a field belonging to a private owner. Because the stones lie scattered rather than in place, visitors see a ruin whose slabs are dispersed across the ground, not a standing chamber.

The dolmen stands in a field at the lieudit Béziet, on land belonging to a private owner, so access requires the owner's permission. Ask locally in Voutré beforehand rather than crossing the field unannounced.
