Origin and history
The Kerascouët alignment, also known as Mer er Mohr, is a megalithic alignment located in the town of Erdeven, Morbihan department, Brittany. This monument dates from Neolithic, a period marked by the emergence of agriculture and the construction of monumental stone structures. The alignment consists of eight stones, only two of which are still standing today. Their height varies between 2.20 meters and 4 meters, and the whole is oriented on a south-south-south-west/north-north-east axis.
The complex was listed as historic monuments by an order of 24 July 2023, recognizing its heritage value. This site is part of a regional context rich in megalithic remains, typical of Brittany and especially of the Morbihan coast. These monuments, often linked to funeral or ritual practices, reflect the social and spiritual organization of neolithic communities.
According to available sources, including Philippe Gouézin's work, Kerascouët's alignment is part of a broader set of megalithic sites studied in Morbihan. These structures, often aligned or arranged in circles, bear witness to the astronomical knowledge and beliefs of the people of the time. Their preservation now allows us to study the construction techniques and lifestyles of prehistoric societies in this region.
The site is located precisely on Parcel ZX 108 of Erdeven's cadastre, and its recent inscription as a historic monument aims to protect both the still standing stones and the surrounding soil, potentially rich in archaeological artifacts. This protection is part of a broader approach to valuing Breton's megalithic heritage, which attracts many researchers and visitors every year.
