Roussillon (; ) is a commune in the Vaucluse department of the Provence-Alpes-Côte d'Azur region in Southeastern France. In 2016 it had a population of 1,317. Roussillon lies within the borders of the Natural Regional Park of Luberon. In the French natural regional parks system, new economic activities may be developed only if they are sustainable. It is noted for its large ochre deposits found in the clay surrounding the village. Ochres are pigments ranging from yellow and orange to red. One of the former ochre quarries can be visited via the "Sentier des Ocres" (Ochre Path), a walk of either 30 or 60 minutes through the old workings. Geography The village stands on an ochre ridge, situated in a broad valley with the "Monts du Vaucluse" to the north and the "Petit" Luberon to the south. The nearest railway station is in Cavaillon; the nearest TGV station is in Avignon. The river Calavon forms part of the commune's southern border. Geology Roussillon is famous for the rich deposits of ochre pigments found in the clay near the village. The large quarries of Roussillon were mined from the end of the 18th century until 1930. Thousands of people found work in the quarries and factories. Nowadays the mining of ochre is prohibited here, in order to protect the sites from degradation or even complete destruction. Mining ochre During the 18th century, increasing demand for pigments in the textile industry led to intensified mining of ochres in Roussillon. Numerous quarries and ochre factories, some of which can still be seen today, were situated near the village. One example of an ochre factory, the "Usine Mathieu", is named for the family that owned it from 1870 to 1901. It has been formed into a "Conservatoire": a workshop serving as a museum. The quarries and factories were established in the villages of Roussillon, Villars, Gargas, Rustrel (with its Colorado provençal) and Gignac. During the 20th century, mining techniques were modernized, which meant that more profitable ochre mines became exploitable. This resulted in a gradual closing-down of ochre mines in and around Roussillon. From the 1980s, tourism has replaced ochre industry as a source of income. Agriculture Apart from tourism, agriculture is the commune's principal activity. Fruit, including cherries, peaches and melons are grown. Much of this is used in crystallized fruit production in nearby Apt. Wine-making is very important and there are several
