St. Peter's Basilica, the Vatican

Next up: none other than Mr. Michelangelo Buonarroti, born in 1475 and perhaps best known for his work as a painter and a sculptor. But in addition to decorating the Sistine Chapel and sculpting works like "David," Michelangelo did architectural work for St. Peter's Basilica in the Vatican, as well as other projects such as the Laurentian Library and the Medici Chapel.

His designs helped usher in the age of Mannerist architecture, while adding flourishes that would later influence the artists and architects of the Baroque period. Many post-Renaissance architects -- some even students and assistants of Michelangelo -- would find inspiration in his work, which was never constrained by the stringent doctrines of classical design.
