European megalithism dates mainly from the Neolithic and will last until the Chalcolithic (Copper Age) from 5000 to 2000 BC. Fifty thousand dolmens have been recorded in the world, including twenty thousand in Europe, although these are unevenly distributed according to the regions. The French department with the most dolmens is not found in Brittany or on the Atlantic coast as one might believe it! Finist?re and Morbihan, the two departments with the most dolmens in Brittany, each have around 350 dolmens, where the south of France has several thousand. The Aveyron is the leader with about 1000 dolmens, followed by the Ard?che and the Lot with about 800 dolmens each. Megalithism developed where humans could easily extract and transport large slabs of stone. In Aveyron, these technical constraints explain the concentration of megaliths on the Causses de Villeneuve and the Causse de S?verac, limestone rock being the most commonly used material in the megalithic period, thereby confirming the "law of limestones". The Aveyronnais dolmens are small dolmens, mostly of the simple dolmen type, with a very often rectangular plan. This book presents the location, map in support, dolmens of Aveyron department (12 - France) classified or listed as Historical Monuments.
