Follow the coast road north from Trébeurden and when you reach Penvern take the left turn signed to Île Grande. Follow the road for about 0.5km and look for a small layby on the left. The sign to the tomb is very small and easy to miss and this sign is just beyond the parking space. A small gap in the hedgerow leads to the tomb that is about 100m from the road.
This is an excellent site. The tomb has been restored after it was excavated in 1965. It is aligned ESE to WNW with the entrance to the east. There is a long rectangular chamber leading to a blocked end chamber. A large transverse stone blocks it. The chamber is about 10 by 2m (34 by 6ft) and is lined with granite slabs and has seven capstones. To the east of the entrance is a small standing stone.
The small end cell is interesting as three of the stones are carved on the inside. It is triangular in shape and has a capstone and the only way in is quite a tight squeeze through a gap in the side.
The gap in the side of the end chamber
In this small cell you can see the carvings quite clearly. The back of the blocking stone has a pair of rectangular figurine forms that also have very small cupmarks on their inner faces. Between them near the ground is a spearhead shape carving. The side slab to the left has a dagger shape and a pair of breasts carved with a curved shape below them like a necklace. The stone to the right has two more pairs of breasts clearly carved in a deep recess – they are quite pronounced.
