Perhaps because it was just named to the list of the New 7 Wonders of the World, the Colosseum has joined the online age. You can now buy tickets in advance to visit the Colosseum via a couple of websites (here and here).
As the websites are not limited to just the Colosseum, it’s possible to buy multiple advance tickets for various sights throughout the Lazio and Campania regions. Depending on the season, advance ticket purchases may or may not be necessary. During the high season, however, they’re often a must. It’s great that the Colosseum has joined the ranks of Florence’s Uffizi in terms of helping visitors spend more time seeing the sights and less time standing in line for them.
I’ll now be updating my guide to visiting the Colosseum accordingly!
One note: I’ve not personally used these services, so I can’t vouch for them myself. If anyone has personal experience with doing this, please let me know.
