Coming soon descriptions of the Colosseum and more information. Until then enjoy the links below.
Link to the official site of the Colosseum.
This page is great in many ways (the plans alone are wonderful to look at), but has some places where it has to be treated with caution. If you’re interested in seating at the Colosseum, then I recommend, Jonathon Edmundson’s wonderful article on seating and Roman society. It’s helpfully available as a .pdf at the above link and is something you really should read about to understand the complex social relations on view at Roman games.
