Of course, the Colosseum and Roman Forum are must see visits on any trip to Rome. The Colosseum is a symbol of the ancient Romans, iconic of their wealth and engineering ingenuity. The Colosseum is also symbolic of immense cruelty, where spectacles, gladiatorial fights and executions occurred. It speaks a lot to our progress as human beings that the Colosseum is now used as a beacon for the worldwide anti- death penalty movement; whenever the death penalty is abolished somewhere in the world, or a sentence is commuted, the stadium is lit in gold.
For entering the Colosseum and Forum, you can get a Roma Pass. The good thing about the Roma Pass is that you get to skip the ticket line, since the lines in Italy are often divided into two-- one line to buy a ticket and one queue to enter.
Right outside the Colosseum subway stop you will be greeted by the structure.
You can take a walk around and see the different walls. The inner wall is mostly intact but the outer wall is only partially remaining.
You can walk around on two different floors inside.
Outside the Colosseum, up the road is the Roman Forum. It's a really massive area that was once the city centre of Rome. Here's a map with all of the sights.
Here's a view from the Musei Capitolini, which I'll write about next week (Live 22nd of Dec. Follow me on Facebook to keep hearing updates)!
