San Giovanni in Laterano

This is the cathedral church of Rome and first of the major basilicas. It's also the Pope's (as Bishop of Rome) Church. As such it ranks above all other churches in the Roman Catholic Church, even above St. Peter's. Be sure to check out the 4th-century baptistery (still in use - in Piazza di San Giovanni, slightly apart from the main basilica) and the medieval cloister (brilliant Cosmati columns)
