Visitors to St. Peter’s Basilica in Rome often don’t realize that the magnificent baroque church is built over the site of a still more ancient basilica, built by Constantine and then torn down completely by Pope Julius II during the Renaissance. Over the course of the next century, today’s basilica was rebuilt by the likes of Bramante, Giulio da Sangallo, Raphael, Michelangelo, Carlo Maderno, and Bernini.
Surprisingly little of the original church remains, so I was fascinated this week to see a few of the mosaics saved from the first basilica at a special exhibition on medieval Rome at the Museo di Roma. The exhibition displayed work from the other four major basilicas, each of which has a unique history. The complex around St. John Lateran, another Constantinian construction, has changed greatly over the centuries and the interior of the church was redone by Francesco Borromini in the 17th century, though the shape of the basilica remains basically the same. St. Mary Major preserves the magnificent mosaics from its Roman days, but St. Paul Outside the Walls was entirely rebuilt after a fire burnt it down in the early 1800s.
Here are a few pictures form the papal basilicas’ medieval past.
