Amphitheatre

An amphitheatre was a type of outdoor theatre. It was particularly favoured by the Romans as a place of gladiatorial combat. Ian Chesterton, for instance, was once forced to fight another gladiator for the amusement of Caesar Nero in a 1st century amphitheatre. Chesterton only narrowly escaped having to fight a lion there. (DW: The Romans) In the 2nd century, the Tenth Doctor actually did have to face a lion — as well was a tiger and a bear — in a different amphitheatre. (NSA: The Stone Rose)
