Does anyone recall the name of the abovewhere he had to renounce his belief that the earth revolved around the sun? I recall reading this (and I visited the church in Rome!) in a RS book; I'm returning to Rome in a few weeks and would love to visit it again, but I can't recall which church it is! Google didn't yield much for me...
Santa Maria sopra Minerva Recantation of Galileo
The RS Rome book also has an excellent self-guided tour called the Pilgrims' Walk of Rome, or something like that. Very well done, but be sure to read the church hours, as a lot of them close around noon and don't reopen until 4 or so in the afternoon.
