Dolmen of Pen Liouse

A distinctive group of dolmens and banks

On the southern end of the island there is a unique group of megaliths. Three ruined dolmens are set into a large stone bank. These three graves were excavated in 1884: pottery, fragments of flint and axes were found. These are now preserved in Vannes History and Archeology Museum. The objects discovered date the monuments to the Neolithic Era, between 5000 and 2500 BC.


The central dolmen, which is the best preserved, features a few eroded engravings. There are some scattered stones around this group; these may be the ruins of other megalithic structures.
