Mystery of the buried chamber at the Dolmen of La Pineyre

The Dolmen of La Pineyre, known as the tumulus-dolmen of la Pennet (de la Bonnet), is a mysterious Neolithic structure located in the heart of Saint-Nectaire, France. It was classified as a historic monument in 1923 and dates back to around 4500 years ago. The architecture of the dolmen is complex and largely hidden within its tumulus, with at least 4 orthostates and a heavily inclined table that rests on the structure's supports. The table, from the outside, measures a maximum of 4.20 meters in length, 3.60 meters in width, and 1 meter in height.

The chamber, with the table's inclination, measures 3 meters in length, 2.50 meters in width, and 1.50 meters in height. The chamber opens towards the southwest between the stones number 1 and 2, but it may not have been the original entrance. The tumulus is well preserved, with a diameter of 6 to 8 meters today, although it has been damaged by landslides and the creation of a forest path nearby. The dolmen was unfortunately once targeted, with its burial chamber excavated and its contents stolen, leaving no trace of its archaeological furniture.
