The Basilica is best known for its other treasures, including mosaics of the nave and triumphal arch connecting the sanctuary that date back to the pontificate of Pope Sixtus III (432-440). The mosaics in the apse of the sanctuary were commissioned by Pope Nicholas IV (1288-1292). The ccsmatesque floor of the nave and the gilded wooden ceiling are absolute masterpieces. Other majestic works of art include the Nativity scene by Arnolfo di Cambio. Every single column, painting, and statue encompass centuries of devotion and religious fervor.
The sublime travertine mantle that covers front of the Basilica is the first sight visitors encounter as they arrive and enter -- the imposing facade, conceived by the architect Ferdinando Fuga for the Jubilee Year 1750. In its upper loggia it houses mosaics that date from about 1290. Although this special area is closed to the public, it is possible to access through a VIP tour that includes a visit to the rooftop of the Basilica.
Those who take this tour visit the so-called 'Hall of Popes,' located just off the front loggia. This unique room houses some important vestments from the tesoro of the Basilica, if not the greatest of its vestment collections that have survived the centuries. These vestments are made of pure red, white, green, and violet silk. Their embroidery was done in real gold and silk thread. They were crafted in seventeenth century Italy. One depiction of the coat-of-arms is that of Scipione Cardinal Borghese, taken from his uncle Camillo Card. Borghese (Pope Paul V) -- seen on the green and violet chasubles; a gold dragon surmounted by a black eagle.
These precious treasures are kept in two massive custom-made wooden vestment cabinets completed for the canons of the Basilica in 1628. Below are several images of the vestments. The room was designed by Pope Paul V (1605-1621) with a marble fireplace installed in 1605. The marble floor is the newest part, completed under the reign of Pope Paul VI in 1969. This room is the most representative of the architectural project that was commissioned by Paul V in the early 1600s when he had the palace built here around the Basilica for the exalted canons.
The architect chosen was Flaminio Ponzio, from Lombardy. The room is part of a large five-story palace plan where the canons were intended to live. The hall has paintings of illustrious personalities linked to the Basilica over the centuries. These include cardinals such as Charles Borromeo who was once the Archpriest. There are also images of popes and members of the royal family of Spain who were devoted to the Basilica (the Spanish king remains to the his day the "protocanon").
An elegant spiral staircase, off to the side, is attributed to Bernini. It connects the five levels of the palace with the new sacristy below on the main level. Its form, made without columns, is reminiscent of a stretched shell and its lines follow an upward direction, symbolic of the path from earth to heaven, from darkness to light. We hope visitors will enjoy the photos and rare glimpse of filigree tracery in gold and silver wire, emanating a distinguished shine.
