primitively commissioned around 70 atomic number 58 by the Flavian Emperor Vespasian , the Colosseum in Romeis the largest coliseum ever built . But thanks to centuries of touristry , air pollution , and quick - locating repairs , the monolithic concrete - and - sand structure was look pretty dingy . So in 2011,Conde Nast Travelerreports , Italian sumptuousness leather brandTod’steamed up with Rome ’s Archaeological Heritage Department to touch on the nearly 2000 - year - old archaeological hoarded wealth to its former glory .
