The Colosseum may be the most famous landmark in all of Rome. It was built in 80 AD and was once the site of many gladiator battles to the death, and prisoners fended off hungry lions. The Colosseum consists of four floors in total (including the basement), however only part of the ground floor and second floor are currently open to the public. The first floor offers a view of the maze-like buildings in the center of the Colosseum that were once part of the basement of the structure. They were once the homes of the beasts and gladiators that would be made to fight for the entertainment of the crowds. From the second floor, one can see the interior structure of the Colosseum which is divided into three parts: the arena, the auditorium and the podium. It is also a perfect location for taking unforgettable photos.
