Cromlech de Kergenan, Prehistoric stone circle in Île-aux-Moines, France.
The megalithic structure consists of thirty-one standing stones arranged in a circular pattern, with twenty-four stones remaining upright on the island.
First documented in 1827 and classified as a historical monument in 1862, this megalithic site underwent extensive archaeological excavations by A. Mauricet in 1877.
The stones, reaching heights between two and three meters, create a circle measuring one hundred meters in diameter with an opening toward the southeast.
The site is divided between private property and public access areas, with the accessible portion managed by the Morbihan department administration.
Studies conducted by René Merlet in 1922 revealed potential alignments between this structure and neighboring megalithic monuments in the region.
