The Sistine Chapel ceiling, painted by Michelangelo between 1508 and 1512, at the commission of Pope Julius II, is one of the most renowned artworks of the High Renaissance. The ceiling is that of the large Papal Chapel built within the Vatican between 1477 and 1480 by Pope Sixtus IV after whom it is named the Sistine Chapel. The chapel is the location for Papal Conclaves and many important services. vi wiki
