Check Out The Colosseum
Ticked off in February 2015
What it is
The Colosseum is the largest amphitheatre ever built, opened in AD 80 and able to hold more than 50,000 spectators.
How to do it
Book timed tickets online. Guided tours can take you to the underground chambers and arena floor.
Top tip
The ticket usually includes the Roman Forum and Palatine Hill, so allow time for those too.
My experience
Ticked off, but the full story is still to be written up.
