Comprégnac is a town located in the Regional Natural Park of Grands Causses on the right bank of the Tarn, 12 km west of Millau.
In 1366, the castle belonged to Bertrand de Luzençon; this family melted into one of the Vezins Lévézou. There are still some remains of the castle in this village.
Valley of the right bank of the Tarn, Millau downstream, is the territory of the Causse Rouge. These terraces are favorable to growing vines for the production of the coasts of Millau, and planting truffle oaks.
