Mougau-Bihan gallery grave

The Mougau-Bihan gallery grave, also called Ti Lia Ven, is a covered alley tomb in Commana in the Finistère department of France. The site is listed as a historic monument.

The monument was mentioned in 1843 by Jean-Baptiste Ogée. It may have been excavated in the middle of the nineteenth century, but the outcome of any excavation is unknown. Jean-Marie Abgrall gave the first description in 1884. The gallery grave was listed as a historic monument by decree of 14 June 1909.

The gallery grave runs north-south and opens to the north-northeast. It measures 14 m long, with an internal width of 1 to 1,40 m. It is bounded by eighteen orthostats, ten on the east side and eight on the west. It consists of a rectangular chamber, 11 m long and 1,50 m wide, and a rectangular terminal cell, 2,30 m long and 1,40 m wide. The presence of a vestibule is suggested by a first pillar that projects beyond the first capstone. The entrance's eastern pillar is set at an angle and narrows the passage. A terminal slab separates the chamber from the terminal cell. Five granite capstones cover the structure, four over the chamber and one over the terminal cell.

Several slabs carry bas-relief sculptures. The angled entrance pillar has two pairs of superimposed breasts and a "palette" on its outer face. The last slab on the east side of the chamber has two further palettes, while the terminal slab carries a central sculpture of an axe with a curved handle in the shape of a crook. By comparison, the monument was dated between 3 000 and 2 500 av. J.-C. The record gives a broader dating of 4500 BCE to 3300 BCE based on typological estimate.
