Alignement de menhirs de Pleslin-Trigavou

The megalithic alignment consists of 65 white quartz blocks arranged in five parallel lines extending over 155 meters across the field.

The stone alignment dates back to the late Neolithic period between 2000 and 1700 BCE and received historical monument status in 1889.

The local community organizes an annual megalith festival in July to celebrate and preserve the archaeological heritage of the stone alignment.

Among the 65 stones, 55 menhirs lay on the ground, while the largest standing stone measures 3.5 meters high, 2.5 meters thick, and 1.5 meters wide.

Local folklore suggests that fairies dropped these stones while transporting materials intended for the construction of Mont-Saint-Michel.
