In this twenty-year period, Rome became one of the greatest centres of art in the world. The old St. Peter's Basilica built by Emperor Constantine the Great (which by then was in a dilapidated state) was demolished and a new one begun. The city hosted artists like Ghirlandaio, Perugino, Botticelli and Bramante, who built the temple of San Pietro in Montorio and planned a great project to renovate the Vatican. Raphael, who in Rome became one of the most famous painters of Italy, created frescoes in the Villa Farnesina, the Raphael's Rooms, plus many other famous paintings. Michelangelo started the decoration of the ceiling of the Sistine Chapel and executed the famous statue of the Moses for the tomb of Julius II.
