The dolmen Peyre-Brune is situated next to a forest track leading from Seyssac, a little hamlet in the commune of Saint-Aquilin, to Segonzac.
The dolmen is completely surrounded by woods and is positioned on a topographic high at about 200 meters above sea level.
The stones consist all of the same material - a very hard, silicified and iron-bearing, very fine-grained sandstone of orange-brown colour, which explains the dolmen's name.
[1] This very hard stone was much appreciated by the megalithic builders, and Peyre-brune is not the only structure, where the sidérolithique was used (another example is the dolmen Peyrolevado near Paussac).
Excavations by the Societé archéologique du Périgord in 1874 unearthed the following objects: Furthermore, were found stone fragments, plant ash and charcoal derived from oaks.
