【羅馬】古羅馬競技場

It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world, despite its age. The Colosseum is built of travertine limestone, tuff (volcanic rock), and brick-faced concrete. It could hold an estimated 50,000 to 80,000 spectators at various points in its history,having an average audience of some 65,000; it was used for gladiatorial contests and public spectacles including animal hunts, executions, re-enactments of famous battles, dramas based on Roman mythology, and briefly mock sea battles. Although substantially ruined by earthquakes and stone robbers taking spolia, the Colosseum is still a renowned symbol of Imperial Rome and was listed as one of the New 7 Wonders of the World.The Colosseum is depicted on the Italian version of the 5 euro cent coin.
