Very few buildings are as iconic as Vatican City’s St. Peter’s Basilica. The art and architecture are a must see.
The site of the Basilica is historically very near to where Peter was martyred during the reign of Nero. The Basilica was first commissioned by Emperor Constantine in the year 324 A.D. and construction was completed in 329. Over a thousand years later, it was decided that the Basilica should be rebuilt because of age deterioration. Construction of the Basilica that we see today was started in 1506. Many of the greatest Renaissance artists took part in shaping it. The Basilica was finished in 1612, while the colonnade in front of it was later constructed from 1656-1667.
