It is better to enter from Europe Square, the top entrance is from the north, it is not crowded there. We buy the ticket online, there is a link at the entrance. The Internet is really weak, after scanning the link it is better to go higher for payment. The place is powerful, especially the stole.
You buy a shared ticket to the Colosseum, the Roman Forum and the Stole. The territory is large, but very interesting. Think of a snack: nuts, snacks, since there are no cafes on the territory and you will definitely get hungry. There are many facilities on the territory, a park, an observation deck. Very interesting.
A unique place in Europe, where you can stand at the origins of European civilization in the full sense of the word. And Italians are surprisingly sensitive to these noble columns and porticos.
