Looking for another unique way to visit the Colosseum—and its underground? How about at night?

Not for the first time, but now nightly until October 5, Rome is opening up the Colosseum to nighttime visitors. Talk about a more tranquil, and spookier, way to visit Rome's bloodiest and most depressing  most famous archaeological site. 

The catch: because the visit includes the underground, it has to be on a tour led by a Colosseum official, which has its pluses and minuses.* Available times are at 8:20pm, 8:30pm, 8:40pm, 8:50pm, 9:20pm, 9:30pm, 9:45pm, 10pm, 10:15pm, 1o:30pm, and 10:45pm. Booking is required; reserve your spot by calling +39 0639967700. The cost is €20, including your Colosseum ticket.

*Pluses: You'll almost certainly get more information on a tour with an official guide than, say, from a guidebook. Minuses: The official guides do this tour over and over and over, meaning the million-and-first time they give the tour—in other words, when you happen to be on it—they often have very little enthusiasm for the subject left. Also, their English can be middling to poor.
