Largest amphitheater - The Flavian amphitheater or Colosseum of Rome, Italy covers 5 acres and originally could seat over 50,000 spectators. Construction began between A.D. 70 and 72 during the reign of Vespasian and the final story was added in A.D. 82, two years after the official opening by Titus. Although originally the scene of keen contests and fierce battles, Christians no longer fear this arena. (Photo: Spectrum Colour Library)
