The Dolmens de La Grosse Pérotte et La Petite Pérotte are a pair of megalithic tombs located in the commune of Saint-Martin-de-Londres in southern France. Dating back to the Neolithic period, around 3500 BCE, they consist of several large standing stones supporting a large flat stone that forms the roof of the chamber. The sites are notable for their well-preserved carvings, which include geometric shapes and animal figures. They are believed to have been used for burial rituals and are part of a larger complex of megalithic sites in the area.
