The Dome

One of the most famous features of St. Peter's Basilica is the dome which was designed by Michelangelo and completed in 1590. It is one of the largest domes in the world and can be seen from many places in the surrounding regions. The dome appears to be upside down, with the oculus being the only thing that pierces through it. It is supported by four great piers which were executed in Bramante's design before Michelangelo took over. The interior of the dome was painted by artists such as Sandro Botticelli, Pietro Perugino, Domenico Ghirlandaio, and Michelangelo himself.

Michelangelo's Pieta

Pieta is a famous Renaissance sculpture that is attributed to Michelangelo Buonarroti,  created between the years 1499 and 1500. Housed in St. Peter’s Basilica, the sculpture is a beautifully detailed representation of the Virgin Mary mourning over the body of Jesus Christ. It is carved from a single block of Carrara marble and was one of Michelangelo's earliest and most outstanding works. Although the artist created many more pieces with the same theme, the Pieta was the first of its kind. You can spot the sculpture to the right of the main entrance as you enter the basilica.

The Papal Altar

You will find the Papal Altar at the center of Saint Peter's Basilica, where only the Pope performs Mass. It was designed by Bernini to be an apse containing a much smaller elliptical one, called the "Altar of the Chair." Two main features of the Papal Altar are St. Peter’s Baldacchino and St. Peter’s Chair. Below the Altar resides the treasured tomb of St. Peter, which makes this Altar a very significant part of the basilica. The Papal Altar was also where the coronation of new Popes took place up until 1963.

Bernini's Baldacchino

This massive bronze structure was designed by Bernini and completed in 1633. It is located just in front of the Papal Altar and was commissioned by Pope Urban VIII as a grandiose way to celebrate the basilica's completion. The Baldacchino is made up of 4 columns, each standing 12 meters high, which are adorned with Corinthian capitals. It is made from 700 kg of bronze and gilded in gold which was donated by King Henry IV of France. Aside from its indistinguishable beauty, the Baldacchino is a special part of the Church because it was built right above the Tomb of St. Peter.

St. Peter's Chair

St. Peter's Chair or the Chair of Saint Peter is an important relic inside St. Peter’s Basilica, allegedly dating back to the 1st century. The term ‘St. Peter's Chair’ or ‘throne of St. Peter’ signifies the fact that Rome has been and continues to be the Church founded by Peter. It is believed that the chair was used during preachings by the Apostle himself, and so it only made sense to have the chair be placed at the site of his burial. Bernini was given the task of highlighting the importance of the Chair. He built a grand structure to enclose the throne and placed it at the end of the central nave.

The Tomb of St. Peter

St. Peter was one of the 12 apostles and a very close friend to Jesus Christ, accompanying him on several religious journeys before his crucifixion in 33 AD. According to legend, while visiting Rome he was imprisoned and executed by Emperor Constantine I. His remains were buried in a cemetery on the Vatican hill, but it wasn't until centuries later that they were finally moved to their current resting place in St. Peter's Basilica. The tomb is located in the apse of the basilica inside the Vatican Necropolis and is often adorned with fresh flowers from visitors.

Althought the Confessio has existed since the foundation of the basilica was laid, the many additional decorations were added during the reign of Pope Clement VIII and Pope Paul V.

Statue of St. Longinus

St. Longinus was a Roman centurion who lived during the time of Christ. His actual name was unknown and so he was named Longinus.
