The name "Óbidos" is a Latinised (oppidum, citadel) derivation of the older Celtic "Eburobricio". The municipality grew from a Roman settlement near the foothills of an elevated escarpment. The region of Óbidos, extending from the Atlantic to the interior of Estremadura Province along the rivers and lakes has been inhabited since the late Paleolithic. A settlement, constructed by early Celt tribes, was later a centre of trade for the Phoenicians. Archeological evidence from the base of the medieval tower (south of Facho) at Óbidos Castle indicates Roman construction linked to an outpost of the Roman civitas of Eburobrittium, a large urban area that has been under excavation. Archeological surveys determined the remains of a forum, baths and other Roman structures near the settlement. More information...
