The highest point in the village of Roussillon is its castrum equipped with an orientation table from which visitors enjoy a 360° panoramic view of the valley and Mont Ventoux. The legend has it that Lady Sermonde threw herself from this 131 ft (40 m) high cliff upon the death of her young lover Guillaume de Cabestan and that her blood colored the surrounding lands with a flaming red. A spring would have gushed out at the exact spot where her body touched the ground.
