Pierre Droite, Neolithic menhir in Milly-la-Forêt, France.

Pierre Droite, also called Pierre du Paly or the Milly menhir, is a single upright block of siliceous sandstone on the plateau above the Essonne valley. It measures about 4 m high, 1.90 m wide at the base and 0.60 to 0.70 m thick, roughly rectangular, pale grey and mottled with lichen. Both main faces carry pecked carvings: a cross above a rectangular base with cupules on the west face, a face with a hairstyle on the east face. A second block of similar size lies on the ground.

The stone was erected during the Neolithic period when early inhabitants placed large stones to mark their presence and land. This practice shows how communities established territory and gathered for important occasions.

The menhir is also called Pierre du Paly or menhir de Milly. Its two main faces carry carvings made by pecking the stone: on the west face a cross rising above a rectangular base with cupules, on the east face a face topped by a hairstyle. It has been classified as a monument historique since 1974.

The site is accessible by train via stations at Maisse and Buno-Gironville on the RER D line. Since the stone stands outdoors in an open area, wear sturdy shoes and dress for changing weather.
