Dolmen d'Ar Roc'h

The stone structure consists of a massive capstone weighing 7 tons, supported by four vertical stones forming a square burial chamber measuring 2.20 meters on each side.

In 1918, archaeologist Zacharie Le Rouzic found fragments of a red clay bell-shaped vessel decorated with dotted lines dating from the late Neolithic period.

The megalith features twenty-five cupules of various sizes carved on the interior face of the southwestern orthostat, indicating ritual or astronomical purposes.

The exact location of the dolmen can be found at coordinates 47 degrees 42 minutes 38 seconds North and 3 degrees 27 minutes 20 seconds West.

The surrounding cairn maintains its original diameter of 8 meters, making it a complete example of Brittany megalithic architecture.
