The name's a little misleading – the Vatican Museums are the home of the Catholic Church's huge collection of priceless art and sculpture, and are found inside the Vatican City itself. The museums are all in the same vicinity, not scattered in different locations. The Vatican Museums are made up of galleries, rooms, courtyards, towers, staircases, chapels, and more.
The Vatican Museums collection began in the early 16th century when Pope Julius II purchased the famous ode to snake-wrestling, Laocoön and His Sons.
Holders of Vatican Museums tickets can explore a trove of religious art, which now houses masterpieces by everyone from Michelangelo to Raphael and Bernini. And, of course, it's home to the world-famous Sistine Chapel and its wonderful ceiling, which is gawped at by as many as 25,000 people every day.
