Visiting the Eternal City and not making a stop at the Vatican Museums is almost like breaking one of the ten commandments. On the last Sunday of the month, you can visit the Vatican Museums for free. It's where some of the world's greatest art collection is stored. The Vatican Museums are actually apart of the Vatican palaces, where popes have lived since the 1200s. Inside you'll find works such as Egyptian relics, Etruscan artifacts, Renaissance paintings and Greek and Roman sculptures and busts, all housed in maze of apartments, galleries and palaces. Let's also not forget about, perhaps what many consider to be the true gem of it all, the Sistine Chapel where Michelangelo's famous Last Judgement can be seen. From Monday to Saturday (9:00am-6:00pm), last entry is 2 hours before closure time. If visiting the museums on anyday but Sunday, it's wise to book your tickets online(http://biglietteriamusei.vatican.va) if you want to avoid having to wake up at the crack of dawn to wait in line for a couple of hours. Buying your tickets online only costs you €4 more than what you'd pay at the ticket booth and is definitely worth it as you get to skip the line. Metro: stations Ottaviano-Musei Vaticani; Cipro.
