The Church of St. Peter in Chains

This ancient church is right across the street from our hotel. I had to climb these stairs to the sound of accordian music played by a street musician. The inside of the church contains this glass case with the chains that supposedly were clamped on St. Peter when he returned to Rome and, ultimately, to his martyrdom. There are about 500 churches in Rome, and, thus far, none of them charges an entry fee.
