Castelo de Óbidos

You can walk around the unprotected Muralha de Óbidos (wall) for uplifting views over the town and surrounding countryside. The walls date from Moorish times (later restored), but the castelo (castle) itself is one of Dom Dinis’ 13th-century creations. It has a stern edifice, with lots of towers, battlements and big gates. Converted into a palace in the 16th century (some Manueline touches add levity), it’s now a deluxe Pousada do Castelo de Óbidos.
