History
A World War I soldier from 1916 was sent back in time by a Weeping Angel and appeared in the Colosseum in 97. He found himself in the middle of a battle between two gladiators. (COMIC: The Weeping Angels of Mons)

In 120, the Colosseum was known as the Flavian Amphitheatre. That year, the Tenth Doctor faced a lion, a tiger and a bear in the amphitheatre. (PROSE: The Stone Rose)

It remained long after the fall of the Empire, though by the 21st century it was partially ruined. On 25 December 2006, when the Sycorax used their blood control technique on Earth, people with A-positive blood stood on top of the Colosseum, ready to jump to their deaths. This plot was stopped by the newly-regenerated Tenth Doctor. (TV: The Christmas Invasion)

Monty Punnions stole the Colosseum and made a replica of it on Phwillite, where Professor Rulas used the landmark as a giant arena where his super computer the Colossus selected players in an effort to find the strongest and bravest fighters in existence. Those selected were placed in the arena, the last man down being named champion of the universe. The Colosseum was abandoned when Rulas was tricked into becoming a competitor and shut down the Colossus in order to survive. (COMIC: Colossus of the Colosseum)
