History

After the Crucifixion of Jesus, it is recorded in the Biblical Book of The Acts of the Apostles that one of Twelve Disciples, Simon who is known as Saint Peter, a fisherman from Galilee, took a leadership position among Christ's followers and became of great importance of the founding of Christian Church.  
Saint Peter




'Petrus' in Latin and 'Petros' in Greek has derived from 'Petra' which means 'Stone' or 'rock' in Greek language.
Catholic traditions hold that Peter, after a Ministry of Thirty-Four years, on 13 October 64 AD travelled to Rome and had encountered his martyrdom there along with Paul during the reign of Roman Emperor Nero. His execution was one of the many martyrdoms of Christians following the Great Fire of Rome. Peter was crucified Head Downwards by his own request as he considered  himself unworthy to die in the same manner as Jesus.

Architecture of Saint Peter's Basilica

Donato Bramante, also spelled Donino was the architect who introduced the high renaissance style in architecture. His early works in Milan included the rectory of Saint’Ambrogio and the church of Santa Maria Delle Grazie. In Rome, Bramante served as principal planner of pope Julius 2nd's comprehensive project for rebuilding the city. St. Peter’s basilica, of which he was the chief architect, was begun in 1506
The basilica is designed as a three-aisled Latin cross with a dome at the crossing, directly above the high altar, which covers the shrine of St. Peter the apostle.

Pope Julius' scheme for the grandest building in Christendom was won buy Bramante out of number of entries. In 1506 foundation stone was laid. The dome was inspired by the pantheon The only difference between Pantheon and Saint Peter’s is that the pantheon is supported by a continuous wall, whereas in saint peter’s, a large Basilica is supported on four piers.

Tufa structures at Mono Lake, California Tufa is a limestone which formed when carbonate minerals precipitate out of ambient temperature water
The equal chancel, nave and transept arms were each to be of two bays ending in an apse. At each corner of the building was to stand a tower, so that the overall plan was square, with the apses projecting at the cardinal points. Each apse had two large radial buttresses, which squared off its semi-circular shape. Bramante was replaced by Giuliano da Sangalio  and Fra Gioondo in 1513 when Pope Julius died followed by the death of them, both died in 1515. Raphael was confirmed as architect of St. Peter's on 1 august 1514. The main change in his plan is the nave of five bays, with a row of complex apsidal chapels off the aisles on either side. 
Bramante's Dome

Bramante's plan for the dome of St. Peter's follows that of the pantheon very closely, and like that of the pantheon, was designed to be constructed in tufa concrete for which he had rediscovered a formula.  The profile is very similar, except that in this case the supporting wall becomes a drum raised high above ground level on four massive piers. The solid wall was at pantheon but in this case a peristyle was used.
