The ocher mines of Roussillon are one of the most dramatic sights I've seen in Provence. For over 2,000 years, people have been mining and using the pigments made from the world's largest known deposit of ocher. There are at least seventeen different hues of the substance and they range from brilliant yellows to oranges, reds, and purples. Besides the colors, the landscape is eroded into a maze of canyons and fissures. You can see more here . And there are some pictures of the village here .
