The factory was originally purchased in 1901 by Camille Mathieu, an engineer who modernized the extraction process.
The industrial site operated for over six decades before global competition and synthetic pigments forced its closure.
Ocher from this region is renowned for its specific chemical composition of iron oxide and clay.
The museum grounds include a conservatory of plants that produce natural dyes, demonstrating the historical link between botany and pigment production.
The site uses its historical sediment basins to demonstrate the traditional 'levigation' technique used to separate fine pigment from sand.
Ôkhra is an ecomuseum located in the former Mathieu factory, a 19th-century industrial site dedicated to the processing of ocher pigment in Roussillon, France. The site preserves the historical machinery and infrastructure used for washing, drying, and milling ocher until the factory ceased operations in 1963. Visitors explore the evolution of color production through original sediment tanks, drying ovens, and crushing equipment. The museum serves as both a cultural repository for regional geological history and an educational center for natural pigment artistry. It is situated within the Vaucluse mountains, a region historically significant for its vast, iron-rich ochre deposits.

Wear comfortable, closed-toe walking shoes as the site covers a large, uneven industrial area.
Participate in a workshop to learn how to mix raw ocher pigments with binders like egg or oil.
Allow extra time to browse the on-site boutique, which sells rare natural pigments and professional-grade art supplies.
Do not confuse this museum with the 'Sentier des Ocres' (Ocher Trail), which is a separate hiking path nearby.
Closed annually for a period in mid-winter; typically operates daily during the peak spring and summer tourist seasons.
Avoid touching historical machinery or exposed raw pigment basins.
