The Coloseum in Rome is the largest ampitheater built by the Roman empire, seating 50,000 patrons. Construction began in 72 AD and was completed in 80 AD, although alterations were made over the years. The wooden floor is gone and the understructure (hypogeum) which was used to hold the animals and gladiators before a show is now visible. AIMG_2253
