A Gallo-Roman capital !
Long unknown, a Gallo-Roman town lies dormant beneath the streets of Carhaix. For several centuries, scholars and historians tried to link the remains of an aqueduct and Roman roads to an ancient city whose name was known thanks to ancient springs and milestones … Vorgium. But it wasn’t until the 1990s, when some preventive archaeological excavations were carried out, that the extent of the town was revealed. A Gallo-Roman capital, that of the Osismii, was therefore unveiled. A town of several thousand inhabitants, even larger than Vannes-Darioritum and at least of equal importance to Rennes-Condate.
But who were the Osismii? This Gallic people lived at the tip of the Armorican peninsula, in an area stretching across present-day Finistère and part of the Côtes d’Armor. At the very end of the 1st century BCE, the Osismii abandoned their ancient oppida, rediscovered by archaeologists at Saint Symphorien en Paule and the Camp d’Artus in the Huelgoat Forest. They reach a newly founded city, a little Rome: Vorgium.
