If you want to avoid the usual Sistine Chapel crowds, here's one way to do it: Go to the Vatican at night.

For the third year in a row, the Vatican museums are having their "extraordinary opening" from 7pm-11pm. Last year, more than 30,000 people took advantage. And whether your day is completely booked or you'd simply like to see the Sistine Chapel and Laocoön in a bit of a more serene atmosphere, now's your chance.

The museums will be open on Friday nights from now until July 15, and then again from Sep. 2 until Oct. 28. Last admission is at 9:30pm.

The areas open in the museums are the Egyptian museum, Pio-Clementine, Galleries of Tapestries, Candelabra, and Maps, Raphael Rooms, Borgia Apartment, Collection of Modern Religious Art, and, of course, the Sistine Chapel. (There's no guarantee, and it's in fact unlikely, that other areas, like the Pinacoteca, will be open).

Tickets must be booked in advance, so the full-price ticket is €19 (includes the €4 reservation fee), or €12 reduced (students, bring your I.D.s!). Click here to book.
