St. Peter's Square (Piazza San Pietro) : mid-17th century (1656 - 1667) by Gian Lorenzo Bernini. Constructed as a public location for the faithful to practice. The square contains a 13th century BC Egyptian obelisk, rising 40 m (131 ft.).
The bronze globe once atop the obelisk is believed to contain the ashes of Julius Caesar, and is now housed in the Capitoline Museums. The cross at the top of the obelisk is believed to preserve a fragment of the True Cross.
Carlo Maderno's Fountain 1611-12 : North of the obelisk
Bernini’s Fountain, 1675 : Designed to compliment Maderno's.
St. Peter's Basilica, 4th century origins, current construction from 1506 : Constructed by Christian Emperor Constantine on the burial site of St. Peter, the first pope. The basilica supports the largest dome in the world (designed by Michelangelo), and can house 60,000 worshippers, making it the largest church in the world. Now home to many important works such as Michelangelo’s Pietà.
Michelangelo's Pietà, 1498 - 1499 : Originally sculpted as the funeral monument for the French cardinal Jean De Billheres, moved to St. Peter's Basilica in the 18th century. Currently protected by bullet-proof glass after being damaged in 1972 by tourist with a sledgehammer.
Sculpture : Throughout the centuries, the Vatican has collected monumental works including monuments to historical figures, in particular a 13th century statue of St. Peter Enthroned by Arnolfo di Cambio which has become famous for its feet being worn down from centuries of visitors rubbing and kissing them. The 30 meter (90 foot) baldachin canopy above the main altar was designed by Bernini (note his fountain in the Square), using bronze from the Pantheon (circa 27 BC).
Holy Relics : The basilica preserves what is commonly believed to be the last remaining fragments of the True Cross (the cross upon which Christ was crucified). For security and preservation, they fragments are only displayed during Holy Week (the week preceding Easter Sunday).
Michelangelo's Dome, mid 1500s : 42.3 meters (138.8 feet) in diameter, 120 meters (393.7 feet) from the floor. 136.57 meters (448.5 feet) from the floor to the top of the cross on the dome. The dome of St. Peter's attracts visitors for its architectural genius, impressive views and long history.
Sistine Chapel, 1368; restored late 15th century : The Sistine Chapel is known for its Michelangelo frescoes, but also contains masterful works by many of the best artists of the day. The Chapel is also popular as the location of the Room of Tears, where newly elected pontiff contemplates his position, chooses his papal name, and dons his cassock for the first time. It is said that three sizes of the holy robes are hung in the room and the pope wears the one that fits best.
