The Colosseum is a massive amphitheatre located in Rome, Italy. It was built by the emperors Vespasian and Titus in the first century AD and could hold up to 80,000 spectators. This iconic structure was used for gladiatorial contests, animal hunts, and other public spectacles. Over time, it fell into disrepair but still remains a symbol of Imperial Rome. Today, it is a popular tourist attraction and even appears on the Italian version of the 5 euro cent coin.
