The Sistine Chapel is part of the Vatican Museums and is named after Pope Sixtus IV (pope from 1471 to 1484). He ordered the restoration of the old Cappella Magna which was carried out by an illustrious list of artists including Botticelli, Perugino and Domenico Ghirlandaio. The chapel was inaugurated in 1483 as Our Lady of the Assumption. Julius II della Rovere (pope from 1503-1513) ordered the refinement and redecoration of the chapel decoration and employed Michelangelo for the job.
