The Vatican Museums (Italian: Musei Vaticani; Latin: Musea Vaticana) are Christian art museums located within the city boundaries of the Vatican City. They display works from the immense collection amassed by popes throughout the centuries including several of the most renowned Roman sculptures and most important masterpieces of Renaissance art in the world. The museums contain roughly 70,000 works, of which 20,000 are on display, and currently employ 640 people who work in 40 different administrative, scholarly, and restoration departments. Pope Julius II founded the museums in the early 16th century. The Sistine Chapel, with its ceiling decorated by Michelangelo and the Stanze di Raffaello decorated by Raphael, are on the visitor route through the Vatican Museums. In 2017, they were visited by six million people, which combined makes them the 4th most visited art museum in the world. They are one of the largest museums in the world.
