The Drôme department is found in the very south of the Rhône-Alpes region. Together with the Isère and the Haute-Alpes, it forms the old province of Dauphine, which was dismantled in the aftermath of the revolution. The Drôme is renowned for its diversity, both in terms of its landscape and its culture. The northern part of the Drôme contains many deep, fruit-bearing valleys. Over many years, these valleys have created large circular pebbles that have been put to good use in local construction.
