Château de Calmont d'Olt

The Château de Calmont d'Olt is a castle situated in France, in the Aveyron département in the commune of Espalion.

[citation needed] Flint fragments and a polished stone axe are evidence of occupation of the site for 5,000 years.

It has always had a military significance, commanding the road from Rodez to Aubrac and, more widely, the crossing of the River Lot on the Toulouse-Lyon route.

It bears witness to the architectural adaptations of castles to the technical progress of the Hundred Years' War.

From this date, with the assistance of Bâtiments de France and the regional archaeological service and thanks to the help of volunteers working summers with the castle team, the site has little by little been reborn.
