At the ripe old age of 71, Michelangelo took over the direction of the most important building project in Europe – the Fabbrica of St. Peter’s Basilica. Michelangelo redesigned the great building and saw construction through to the base of the cupola. This project would occupy the last 17 years of his life and consume nearly all his creative energies. This episode examines Michelangelo’s role in the realization of the great basilica, as well as analyzing his revolutionary architectural style that paved the way for Baroque-style architecture in the next century.
