Obidos Castle

Óbidos is a town of approximately 3100 inhabitants and municipal seat of the municipality of Óbidos, located in the Oeste Subregion, of the historical district of Leiria, in Portugal. The name "Óbidos" probably derives from the Latin term oppidum, meaning "citadel", or "fortified city".

Roman occupation of the area was confirmed by archaeological excavations, revealing the existence of a Roman city civitas near the hilltop on which the village and castle were established. This Roman settlement is most certainly the mysterious Eburobrittium, cited by Pliny the Elder as situated between Collipo (near present-day Leiria) and Olisipo (Lisbon). Archeological surveys determined the remains of a forum, baths and other Roman structures near the settlement.
