The current palace was largely constructed from 1309 to 1424 on 9th century origins, designed perhaps by Filippo Calendario.

The Colosseum or Coliseum, originally known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is a giant amphitheatre in the center of the city of Rome. Originally capable of seating 45,000–50,000 spectators, it was used for gladiatorial contests and public spectacles. It was built on a site just east of the Roman Forum, with construction starting between 70 and 72 AD under the emperor Vespasian. The amphitheatre, the largest ever built in the Roman Empire, was completed in 80 AD under Titus, with further modifications being made during Domitian’s reign.
