Origin and history

The alignment of the Champ des Roches, also known as the Druid Cemetery, is a megalithic complex located in the commune of Pleslin-Trigavou, in the Côtes-d-Armor. Ranked a historic monument since 1889, it consists of 65 white filonian quartz menhirs, 55 of which are now overturned. These stones are spread over five rows facing west-east, with a density of fifteen to eighteen blocks per row. The most imposing, called the Tual Rock, is 3.50 metres high for 1.50 metres wide and 2.50 metres thick.

Four other quartzite blocks, located about 100 metres west, could extend the alignment up to 200 metres in length. According to a local legend, these stones were abandoned by fairies during the construction of Mont Saint-Michel. A tradition, still alive in the 19th century, celebrated pagan festivals such as Saint John and Saint Peter, marked by banquets and bonfires, evoking the survival of Druidic rituals.

The site also houses a collection of oaks, integrated into the Botanical Garden of the country of Dinan, including native species (chêne reopens, pedunculate oak) and Mediterranean (chêne-liège, green oak). Owned by the municipality, the alignment is accessible to the public, although its exact location is considered poor (level 5/10) by the cartographic sources.
