The Colosseum was primarily used for gladiatorial contests and public spectacles in Ancient Rome. These included animal hunts, executions, re- enactments of famous battles, dramas based on Roman mythology, and briefly, mock sea battles, which involved filling the arena with water for naval displays. It could hold an estimated 50,000 to 80,000 spectators and was a major entertainment venue. After its use as an entertainment arena ceased in the early medieval era, the Colosseum was repurposed for various uses, including housing, workshops, quarters for religious orders, a fortress, a quarry, and even a Christian shrine. During the Middle Ages, parts of it were used as homes and shops, and it also served as a stronghold for prominent Roman families. The structure ceased to be used for gladiatorial entertainment by the 6th century but remained a significant historical symbol of Imperial Rome. Additionally, the Colosseum has continued to hold cultural importance and is a popular tourist attraction today, symbolizing Rome's ancient grandeur.
