It is said that during Charlemagne's reign, a fortress already stood on this spot overlooking the former road to Brittany. The oldest vestiges, discovered during ongoing archaeological excavation, date back to the 10th century. Ralf de Pomeroy was among the companions who accompanied William on his conquest of England. The family had many possessions in England and founded Val Abbey in the nearby parish of Saint-Omer. The castle and its grounds underwent many transformations up to the 13th century, before being abandoned. Its picturesque ruins, including an impressive porch tower, nestling amidst the woods, are within an inspiringly romantic atmosphere propitious to reverie and legends, including that of Mellia la Blonde.
