Tremeca, Dolmen in Casaglione, France

Tremeca is a dolmen standing in the narrowest part of a small plateau above Casaglione, in west-central Corsica. It measures over 3 m long, 2 m wide and 1.20 m high, with a chamber formed by four rough-hewn granite blocks and an irregular covering slab. The structure opens toward the southeast, and it is unknown whether a tumulus originally covered it.

Roger Grosjean first described the dolmen of Tremeca in his 1966 overview of Corsican prehistoric sites. It was built on a small plateau that served as a passage route, and its chamber is formed by four rough granite blocks and an irregular covering slab. Whether it was originally covered by a tumulus remains unknown.

This site sits within a landscape dotted with stone monuments that early Corsicans built to honor their dead. These structures reveal how prehistoric people organized their communities and marked their connection to the land.

The path to the site is not paved and crosses open terrain, so wear sturdy hiking boots. A map or compass helps because the route is not clearly marked and navigation can be tricky without them.

The dolmen stands in the narrowest part of a small plateau that forms a passage route, which may explain why it was built there. Roger Grosjean first reported the monument in 1966, and it remains one of the few megalithic sites recorded in this little-excavated region, alongside Monte Lazzo.
