The interior church decor was restrained compared to that of other churches in Rome. Near the front is a special glass chest, and inside are chains... they are reputed to be both the chains St. Peter wore in Jerusalem and the chains he wore in Rome - miraculously fused together. Take the story with a grain of salt, but relics and icons are cool anyway. In a side alcove is Michelangelo's sculpture of Moses - incredible. The church is walking distance from the coliseum - actually, most everything in Rome is walking distance from everything else! Go around the corner of the church, down a flight of steps to a main road and there are several good restaurants.
