Castelo de Abrantes
Walk up through the maze of narrow, flower-lined streets to this 16th-century castle, which is still an impressive structure today. The garden between the twin fortifications, with its panoramic views, is a wonderful place to watch the sun set: the play of light on the river and the lengthening shadows along the olive groves provide a stirring setting for an evening picnic. The Gothic church within the castle walls, the Igreja de Santa Maria do Castelo, houses a museum that showcases sacred art from convents and monasteries around the region, as well as items from a large private collection of Iberian art from prehistoric to contemporary times.
