In a partnership aimed at promoting what it describes as 'conscious tourism,' Airbnb has signed a $1.5 million deal with Rome's Colosseum to sponsor a series of staged gladiator fights.

The ancient Roman Colosseum will be the venue of gladiator fights for the first time in two millennia under a $1.5-million sponsorship deal with Airbnb.

A new deal between Airbnb and the Roman Colosseum will let eight people and their plus-ones participate in faux gladiator fights at the ancient amphitheater.
