Origin and history

The covered driveway of Kerbalannec, also known as Ty-ar-C Oriented south-south-east/north-north-west, it is 11 metres long and is bounded by eight orthostats on each side, supporting five granite roof tables. Its entrance, barred by a transverse slab, leaves a narrow passage of 0.50 m, preceded by a short vestibule. A peristalith, vestige of an original terterre, is visible at 1.30 m from the western walls.

Stunned in 1879 by archaeologist Paul du Châtellier, the driveway has delivered a variety of funerary furniture: ceramics (round-bottom vases, jattes, Seine-Oise-Marne type pots and Campaniform tees), lithic tools (dolerite polished axe, fibrolith herminette, flint blades and scrapers), as well as trimmings (fusaiole, perforated pendants). The filling, composed of clay, ash and coal, was 0.40 m below the tables. Du Châtellier noted that the monument, then integrated into a terre, was almost complete despite the disappearance of a southern table.

Ranked a historical monument by decree of January 10, 1924, the alleyway is associated with local legends evoking the Korrigans, Breton mythical creatures. Its alternative name, Ty Ar C Today, the orthostats are (on the road side) cleared, while the site remains a major testimony of neolithic funeral practices in Armorica.

The archaeological sources, including the publications of Paul du Châtellier (1880) and the works of Jean L-Helgouach (1965), underline its importance in the study of Breton megalithic burials. The monument, located along an agricultural path, is partially integrated into a slope, illustrating its insertion into the current landscape. Its furniture, attributed to the cultures Seine-Oise-Marne and Campaniforme, attests to successive occupations between the Middle and Final Neolithic.
