One of the Seven Medieval Wonders, the Colosseum, a giant amphitheatre, is the most recognisable of Rome's classical buildings. It was the first permanent amphitheatre to be raised in Rome, Its original name is Flavian Amphitheatre. It was started by Emperor Vespasian between 70 and 76 AD, and completed by his son, Titus, in 80 AD. The Colosseum was dedicated after Vespasian's death by Titus. He celebrated the opening by holding 100 days worth of games at the place. Originally capable of seating around 45,000 to 50,000 spectators with 80 entrances, it is an inspiration for designers of modern sports stadia. The Colosseum was used for gladiatorial contests and public spectacles.
