the street becomes Rua de S. Paulo (lined with some excellent shops selling antique furniture, porcelain and souvenirs)...ahead is the grand staircase leading to the St. Paul's Ruins (built by the Jesuits in 1602, was destroyed by fire in 1835 except for its stone facade with carvings that tell the story of the Catholic Church in Asia)...Admire the carvings, then visit the restored crypt containing relics of Christian martyrs and a Museum of Sacred Art...
