With fortifications of the probable campings left by the imperial legions from Rome, the town keeps remains of the Gothic walls and the ancient doors of the 15th-16th centuries. Not to miss: Grão Vasco Museum, with important painting collections; the Cathedral, of Romanesque origin; the church of Terceiros de São Francisco, the Néris Convent, and the São Teotónio Hospital. Also worthing a visit are the 17th century church of the monastery of Jesus and the town’s Historic Museum.
