Origin and history

The Lec'h de Kermuster, located in Plougasnou in Finistère, is an emblematic monument of the Iron Age. This erect stone, typical of the Breton megalithic heritage, bears witness to the cultural and religious practices of the Celtic populations of that time. Its inscription as a historical monument by decree of 23 January 1956 underlines its archaeological importance and heritage value.

Lec'h is located at the crossroads of Rue de Saint-Sébastien, in an area accessible to the public. Owned by the commune of Plougasnou, it is referenced under cadastral code D 949. The accuracy of its location is estimated as "a priori satisfactory" (level 6/10), based on available data. This type of monument, often associated with funeral or commemorative functions, reflects the social and spiritual organization of the Iron Age communities in Armorica.

Available sources, including the Merimée and Monumentum base, confirm its protected status and its membership in the communal territory. Although little is known about its precise use, lec'hs (arrested stones) are generally interpreted as territorial markers, funeral steles or power symbols. Their presence in the Breton landscape attests to an ancient and structured human occupation, linked to collective practices and a Celtic cosmogony.
