This basilica was the first Christian church to be built in Rome, commissioned by Emperor Constantine. The church has prevailed through several bouts of adversity, surviving two fires that nearly destroyed it. Fortunately, the church was rebuilt both times in a manner that respected its original design and structure.
The facade features a set of enormous bronze doors that were originally part of the Curia in the Roman Forum. The doors sit below an 18th century portico by Alessandro Galilei and serve as the main entrance to the basilica. The majestic, spacious interior bears the signature of Borromini, who was commissioned in the 17th century to renovate the entire basilica. Marble is the predominant material, which adds to the almost regal quality of the space as does the incredible Giotto fresco that covers the length of one entire wall. A Gothic baldachin hangs above the altar, which is reputed to cover the relics of the apostles Paul and Peter. Only the pope may conduct mass under the baldachin, a privilege that is honoured on every Maundy Thursday.
One of the most impressive sites within the basilica is the cloister. Admission to the basilica is free of charge, but a morning visit to the cloister costs 2 €. The fee is reduced to 1 € if you visit the cloister in the afternoon, shortly before closing time at 6pm. A sense of perfect serenity characterises the cloister, where you can see a number of sarcophagi as well as the personal effects of several pontiffs.
Upon leaving the basilica, make sure to visit the adjacent building, which houses the baptistery.
