Origin and history

The dolmen of Corn-er-Houët, located at Caurel in the Côtes-d'Armor, is a covered alley dated to the recent Neolithic (3rd millennium BC). This funerary monument, classified in 1998, is distinguished by its preserved architecture, including a 22 m long oval tumulus and a peristalith of erect slabs. 10 m long, is bounded by 21 orthostats and partially covered by three displaced cover tables. Its side entrance, southwest side, gives access to a bedroom separated by a central slab.

The site's features include a vestibule decorated with rare engravings, representing patterns in the form of tables of the law, similar to those of Stone Plates (Locmariaquer) or Luffang Tal-er-Roch (Crach). These decorations, unique in Central Brittany, highlight the cultural importance of the monument. The almost intact tart and shale border structures show exceptional conservation for this type of side entrance burial, derived from the local covered aisles under northern influence.

Dolmen has been studied in specialized works, such as the Corpus des signes engraved neolithiques (2017) by Serge Cassen et al., or Les megalithes de l'arrondissement de Guingamp (2006) de Loïc Langouët. Its protection covers the entire burial, including the tart and a 20-metre peripheral strip of land, in order to preserve its archaeological integrity. The site illustrates the funeral and artistic practices of the final Neolithic in Brittany.
