St. Peter’s Basilica

The centerpiece of the Vatican and one of the best places to visit, the magnificent St. Peter’s Basilica was built between the 16th and 18th centuries, replacing earlier structures that began in 326 on what is thought to be where St. Peter was buried. Ironically, it was the selling of indulgences to finance this building in the 16th century that provoked Martin Luther to begin the Protestant Reformation. The work of famous artists begins before you enter the church: in the portico are an equestrian statue of Constantine by Bernini and fragments of a mosaic by Giotto above the main doorway. It’s from the old church, as are the double bronze doors. The huge nave – 185 meters long and 46 meters tall – rises to a dome 119 meters above and can accommodate a congregation of more than 60,000. Compare it to the dimensions of other great churches marked in the floor. On your right, Michelangelo’s famous Pietà, sculpted when he was only 24, is behind reinforced glass. Also on the right is the richly decorated Chapel of the Sacrament, with Bernini’s tabernacle and his rival Borromini’s bronze grille.

Michelangelo’s dome is held on four massive pentagonal piers, and below it, under Bernini’s magnificent Baroque bronze baldacchino (canopy), is the Papal altar. Below is the tomb of St. Peter. The bronze throne in the apse, flanked by papal tombs, is also by Bernini. Tombs of more Popes are in the right aisle. Near the Baptistery are the stairs (a lift is outside near the Gregorian Chapel) to the roof, from which you can climb 330 steep steps inside the dome to the lantern for a closer look at the dome’s structure and magnificent views over St. Peter’s Square. Beneath the church is Vatican Necropolis, the final resting place of several former Popes and said to house the remains of St. Peter himself.

Piazza San Pietro (St. Peter’s Square)

The grand Piazza San Pietro in front of St. Peter’s Basilica was laid out by Bernini between 1656 and 1667 to provide a setting where the faithful from all over the world could gather. It still serves that purpose admirably, and is filled to capacity each Easter Sunday and on other important occasions. The large oval area, 372 meters long, is enclosed at each end by semicircular colonnades surmounted by a balustrade with 140 statues of saints. On either side of the oval are fountains, and in the center is a 25.5-meter Egyptian obelisk brought from Heliopolis by Caligula in AD 39 and set up in his circus. It was moved here in 1586, no small task in those days as the monument weighs 350 tons. The focal point, however, is the façade of the basilica, from whose central balcony the Pope delivers his blessings and announces beatifications and canonizations. From here also, the senior member of the College of Cardinals proclaims the name of a new Pope elected by the conclave.

Vatican Library

The value of its contents makes the Vatican Library the richest in the world, with 7,000 incunabula (printed before 1501), 25,000 medieval hand-written books, and 80,000 manuscripts that have been collected since the library’s founding in 1450. And that’s just the old books; it doesn’t count all the books it contains that were printed since the end of the 15th century. In its 70-meter-long hall, built by Domenico Fontana, you can admire some of its most precious treasures – beautiful hand-illuminated Gospels, Biblical codices, early printed books, parchment manuscripts, and ancient scrolls and papyri. The library also has a recently expanded collection of pontifical coins and medals.

Vatican Necropolis

Beneath the grand dome and priceless frescoes of St. Peter’s, a treasure trove of archaeological finds awaits. Many are aware of the papal grottoes just beneath the cathedral where former Popes have been entombed in private chapels, and the 12th-century church that accompanies them. What some don’t know is that there are extensive ruins, which have been excavated even deeper in the earth below, revealing burial grounds from as early as the 1st century BCE. The deepest of the three levels contains a pagan burial site, and the next level up contains both pagan and Christian graves, as well as ruins including stone crypts and arches dating through the 5th century. The most significant discovery, however, is a gravesite believed to contain the remains of Saint Peter himself, a relic that the Vatican continues to excavate with painstaking care. A limited number of tourists are allowed to visit each day, and tickets must normally be purchased directly from the Vatican Excavations Office, so it is highly recommended that tourists book a pre-arranged private tour of the Vatican necropolis, which will ensure admission.
