Chalencon is located in Haut-Vivarais on the Vernoux plateau, towering the Eyrieux valley with terraced slopes.
The origins of this very beautiful village dates back to the Celts. Then Romans and inhabitants of Gaul built an oppidum.
It became a barony from the 10th century whose most famous baroness was Diane of Poitiers, Henry II's mistress.
Chalencon witnessed numerous wars of religion.
Many vestiges of its marvellous past can still be found in the village architecture such as:
- The Austrian door,
- the royal road with its arcades,
- Renaissance windows,
- the square towers,
- the shop remains.
