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.

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.

Airbnbs are typically synonymous with cozy getaways, but a new Icons experience from the homeshare company is putting guests right in the action with a new Roman gladiator experience in the Colosseum.
