The astounding Sistine Chapel, the apartments frescoed by Fra Angelico, Raphael, and Pinturicchio, some ten museums that include collections of Egyptian, Greek, Etruscan, and Roman antiquities, the renaissance and modern art, and the lush gardens — all make up the magnificent Musei Vaticani. Be prepared to be awestruck!  It will take one at least two hours to see and appreciate many of the works. It is advisable to purchase your ticket online in advance to avoid the queues and it is usually less crowded by mid-afternoon.
