The monument was excavated in 1863 by R. Galles and in 1925 by Z. Le Rouzic. A number of finds were made, including several axes, burnt human bone, arrowheads, 147 callais beards and ceramics. The tomb is covered by a circular mound 25 m in diameter and 5 m high. On top of the mound is a menhir 2.2 m in height that was erected by Rouzic who also reconstructed the cairn.

Kercado - a megalithic passage tomb in Brittany

From a funnel-shaped entrance the 6.5 m long and 1.2 m wide passage leads to the rectangular chamber. The passage is 1.5 m high at the entrance and rises to 2.7 m height in the chamber. This rise from ‘claustrophobic’ low heights to comfortable can be found in many other tombs (i.e. Table-de-Marchants, Gavrinis, Mane Kerioned and many more).

The chamber is 2.9 m x 3.2 m in extend and slightly offset from the axis of the passage. The orthostats of the chamber are decorated with geometric patterns and a ‘figurine’.

The capstone of the chamber is 3.8 x 5.3 m and carved with a 'Manè Retual type axe'. It is quite likely that the capstone was re-used as for other tombs.
