The Colosseum

Anyone who goes to Rome can't miss The Colosseum - the emblem of Rome, and the largest amphitheatre ever built by the Romans.

It's located right in the middle of the city, Colosseo station on metro blue line.

It's one of the most colorful train I'd seen among the Europe metro/underground, covered with graffiti arts.
