St. Peter's Basilica:
It is the world's second-largest Christian church after the Yamoussoukro Basilica in Cote d'Ivoire. St. Peter's is not a cathedral, which is a bishop's principal church. The pope is the bishop of Rome, and his cathedral church is in Rome.
Built on the foundation of the first St. Peter's, the new basilica took 120 years to complete. Masonry, sculpture, painting and mosaic work continued for nearly another 200 years.
The dome of the basilica was designed by Michelangelo, and is 400 feet tall and 138 feet in diameter.
The church is shaped like a cross and is almost 700 feet long, 450 feet wide at its widest point, and stands on more than 18,000 square yards.
In the grottoes or necropolis, beneath the basilica, is a papal burial chamber. The tombs of many popes, including St. Peter (the first pope), are located here.
The Vatican Palaces consist of several connected buildings with over 1,000 rooms. Within the palaces there are apartments, chapels, museums, meeting rooms and government offices.
The Palace of Sixtus V is the Pope's residence.
The Vatican museums, archive, library, gardens and other offices make up the remainder of the palaces.
The Sistine Chapel:
A separate structure from the basilica, designed to be the pope's chapel, was commissioned by Pope Sixtus IV della Rovere.
The Sistine Chapel was designed by architect Giovanni dei Dolci. The decorations by Pier Matteo d'Amelia, Michelangelo, Raphael and others continued for 60 years after construction was completed.
It is the site of the papal conclave and where elections for the new pope are held.
