Yip, and there are no entrance fees at working churches in Italy, unlike the UK.
St Peter in Chains (not far from the Colosseum) houses Michaelangelo's sculpture of Moses. It's, well, very impressive and I think it's the only sculpture of a character from the Old Testament in any Roman church. The other church that fascinates me is the Basilica of San Clemente. The present church is about 1,000 years old, and a C4th basilica lies below it, converted from a Roman house dating from shortly after the fire of 64 CE. The basement of the house was used as a temple by followers of Mithras. 2,000 years of history, and you can still gain access to all the levels.
