Dolmen of Mané Bogad

A dolmen placed on a promontory

The Mané Bogad monument is a passage dolmen. The ruined grave still has its circular burial chamber and an access passage formed by vertical granite slabs. The top of the monument is no longer in place, but the remains of the tumulus covering it can be seen in the form of a mound of earth around the dolmen. This tumulus was surrounded by other small slabs which now form an arc on the eastern side of the dolmen.

This form of architecture is thought to have been developed between 4000 and 3500 BC.

The monument was deliberately built on a promontory, indicating a desire on the part of its Neolithic builders to make it prominent and visible in the landscape.


It has been listed as a Historic Monument since 1931.
