The present day basilica was built under Pope Innocentius II (1138-1148), out of materials plundered from the Baths of Caracalla. The first church on this site dates back to Pope Julius I (the middle of the 4th century AD). Beautiful marbles and sculptures can be admired in the portico, as well as inscriptions which originate from inside the basilica or from the catacombs.
