Óbidos Castle

The name "Óbidos" probably derives from the Latin term oppidum, meaning "citadel", or "fortified city". The municipality had its origin in an early 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 was constructed by early Celt tribes, that was later a centre of trade for the Phoenicians
