The Sargels residual mound

The municipality of Saint-Rome de Cernon originates from the amalgamation of the former municipality of Montclarat with that of Saint-Rome de Cernon, a process which was carried out in 1840. Ever since prehistoric times, humans have inhabited the Saints-Rome area as evidenced by the Sargels caves and the dolmens situated in the bois de Laumière. Human settlement continued during the Roman and Medieval periods as evidenced by the many remains: the Saint-Rome, Mélac, Montclarat and Laumière castles. Today's village expanded in the late 18th century, during the construction of the road from Albi to the Cévennes, and during the construction of the railway in the 19th century. As a result, the village became a place where important fairs and markets were held and has hosted many prospering trading activities.

The Sargels mound, which peaks at 761 m, is residual and was historically part of the Larzac plateau before the surrounding rivers dug their ways through the landscape. It provides a breathtaking view over the Lévézou mounts (snow-capped in winter) to the East, the Larzac foothills to the West and the Merdelou to the South.
