Founded by the Celts in 300 B.C. and a Roman administrative centre in 27 B.C., Bracara Augusta, as the Romans named it, combines the religious importance with today's commercial and industrial prosperity. To visit: the Cathedral (12th-18th centuries), the Treasury and Sacred Art Museum; the Museum at the Biscainhos Palace; and the Dom Diogo de Sousa Museum. Also deserving to be visited are the churches of Misericуrdia (Renaissance), Pуpulo (17th-18th centuries) and of Nossa Senhora Branca (18th century). On the outskirts, 5 km away from the centre, stands the Sanctuary of Bom Jesus do Monte, with its monumental Baroque staircase; the Sanctuary of Nossa Senhora do Sameiro; the ancient Monastery of Tibгes, dating back to the Suevian period and rebuilt in the 11th century, and the Church of Sгo Frutuoso de Montйlios (7th century Visigothic temple).
