Geography The town is situated on the banks of the Rhone, 30 km (19 mi) north of Valence. The Galaure flows north-west through the southern part of the commune, crosses the town, then flows into the Rhone, which forms the commune's western border.

The town covers an area of 464 hectares (1,150 acres) and has just over four thousand inhabitants.

It is the county town of the canton and is important as an administrative, industrial and commercial centre. It has developed in a linear fashion along the bank of the Rhone and has a catchment area of about fifteen thousand inhabitants. It has a number of factories and industrial units making aviation parts, ceramic insulators, nuclear taps, tiles and stationery.

History The Roman town of Ursuli was built on this site at the confluence of the Galaure and the Rhone.

History: Middle Ages The Château de Diane de Poitiers was built in the fifteenth century. It is flanked by corner towers that dominate the Galaure River. The château is surrounded by a landscaped garden designed by Le Nôtre. Château des Rioux is another ancient castle beside the three hectare Parc à l'Anglaise. It originally housed a religious community of monks but was rebuilt in the nineteenth century by Comte Dupeyroux de Salmagne. It offers accommodation in a gite and four guest chambers. The old city walls are still visible on the Place Orsolles and there is a covered market, built in 1852.

History: Modern In the eighteenth century, feldspar and kaolin were found in the area and an industry grew up making hard-paste porcelain fired at a high temperature.

On August 16, 1944, 28 American B17s tried to destroy the railroad bridge, causing many deaths and damage to the south of the town.

More information on the history and the "Montrebut" paleontological site of Saint-Vallier is available in a dedicated room near the local council building.

Fossil site Near Saint-Vallier, on the "Montrebut" hill, there is a fossil bed that serves as a biostratigraphical reference locality. Flowing water has buried the remains of animals over many millennia and careful excavations can help paleontologists understand the relative ages of different rock strata according to the different fossil remains found. This is one of only two locations in which fossils of the extinct badger species Meles thorali have been found.
