Castelo de Abrantes
Walk up through the maze of narrow, flower-lined streets to this 16th-century castle, later used as a military fortress, and which is still an impressive structure today. A deconsecrated Gothic church within its walls, the Igreja de Santa Maria do Castelo, houses the tombs of members of the Almeida family, the leading local nobility. The garden outside the castle, to the right of the entrance, with its panoramic views, is a wonderful place to watch the sun set or enjoy an evening picnic.
