The ‘Jardin aux Moines’ is a megalithic site located on a Neolithic complex known as ‘Buttes aux Tombes’.
This monument appears as a collection of blocks of quartz conglomerate and purple schist, forming a trapezium approximately 25 metres long and 5 to 6 metres wide.
First mentioned in writings from 1825, archaeological excavations were undertaken by Jacques Briard in 1983 and 1984, during which flint arrowheads and pottery fragments were discovered. However, its function remains unclear.
This ‘quadrilateral’ monument is unique, as only two or three other examples are known to exist in Brittany.
The legend of the ‘Cursed Stones of Tréhorenteuc’ from 1863 says that Lord Gastern of Tréhorenteuc and his companions, who led a life of debauchery, were all transformed by divine wrath into blocks of stone during an orgy on All Saints' Day.
Open outside the hunting season, from 1 April to 15 September.
Access from the car park: approx. 100 m walk.
Accessible to people with reduced mobility.
