Colosseum is a massive stone amphitheater in the centre of Rome city. It was built in the 1st century by Emperor Vespasian of the Flavian dynasty as a gift to the Roman people. Built of concrete and sand, it is the largest amphitheatre ever built. The Colosseum is situated just east of the Roman Forum. The Colosseum could hold more than 50 000 spectators. It was used for gladiatorial combats, animal fights and public spectacles. The building ceased to be used for entertainment in the early medieval era. Although partially ruined because of damage caused by earthquakes and stone-robbers, the Colosseum is still an iconic symbol of Imperial Rome.
