Also known as the The Colosseum is an elliptical amphitheatre in the centre of the city of Rome, Italy. Built of concrete and stone, it is the largest amphitheatre ever built and is considered one of the greatest works of architecture and engineering.
The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in 72 AD and was completed in 80 AD under his successor and heir Titus. Further modifications were made during the reign of Domitian (81–96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius).
The Colosseum could hold, it is estimated, between 50,000 and 80,000 spectators and was used for gladiatorial contests and public spectacles such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology.
