The Garden of the Monks

This building appears as a group of granite blocks (white and bulky in the east, in pudding stone of Montfort-sur-Meu and smaller in the west) which are in the shape of a trapezium of about 25 m long on 5 to 6 m large. Archaeological excavations have been done and flint arrowheads and a few fragments of pottery were discovered. But its real function is still unknown. The legend of the garden of the monks": The Lord Gastern de Tréhorenteuc pursued a bad way of life, surrounded by inebriated boors. They were spening all their time having feasts. During an orgy on All Saint's Day, the divine anger was such as they all transformed into rocks.
