Jabron

Highlight • Other

The most beautiful view of the Jabron. The river in the heart of the Drôme connects Montélimar on the Rhône with Comps in the mountains north of Dieulefit over a length of 39 km. At the beginning of the 19th century, ceramic, wool and silk factories were built along the river. The Jabron was the backbone of this industrial development, it provided energy in the form of hydropower and supplied the manufacturing processes with the necessary amount of water available all year round. Since the river is not navigable, the railway line was built.

The Vallée du Jabron meanders through the heart of the western foothills of the French Alps, tightly embraced by mountains to the north and south. The Petit Train du Picodon once ran through the countryside from 1893 to 1936, a train that exuded more romance than speed at just under 15 km/h. The valley, which is very narrow between La Bégude-de-Mazenc and Le Poët-Laval, widens out here in both directions.

Dieulefit Historic Center

Highlight • Historical Site

At an altitude of 400 m, Dieulefit is a tourist and climatic resort which owes its hours of glory to the pottery closely linked to the region. A kaolinite quarry at the bottom of the valley is at the origin of the grouping of potters from the 3ᵉ century. This pottery activity continued over time to reach its peak in the 19ᵉ century. At the beginning of the 20th century, the introduction of new materials led to a change in habits and the Dieulefitoise pottery for domestic use was gradually replaced by tableware. Today, the pottery tradition continues with traditional production and artistic work driven by ceramists and galleries.

Like many estates, Chatêau de Brotin belonged to local nobles before the French Revolution. In this case, it belonged to a hospital order. The current name is due to Aymar de Brotin, a previous owner.

Bégude-de-Mazenc

Highlight • Settlement

The old castle garden in Bégude-de-Mazenc is now public (the old castle has been converted into holiday apartments). The garden is open all year round and there is a bistro (Le Kiosk) near the intersection of rue Émile Loubet and rue Jean Jaurès.
