Colosseum (80). The Colosseum or Coliseum, also known as the Flavian Amphitheatre, is an oval amphitheatre in the centre of the city of Rome, Italy. Built of travertine limestone, tuff, and brick-faced concrete, it was the largest amphitheatre ever built at the time and held 50,000 spectators. The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in AD 72 and was completed in AD 80 under his successor and heir, Titus. Further modifications were made during the reign of Domitian. These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name. The Colosseum could hold an estimated 50,000 to 80,000 spectators during phases of its various renovations over the centuries, having an average audience of some 65,000; it 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. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine. Although substantially ruined because of earthquakes, thieves, and stone-robbers, the Colosseum is still an iconic symbol of Imperial Rome and is listed as one of the New7Wonders of the World. It is one of Rome's most popular tourist attractions and also has links to the Roman Catholic Church, as each Good Friday the Pope leads a torchlit Way of the Cross procession that starts in the area around the Colosseum. In 2018, it was the most popular tourist attraction in the world, with 7.4 million visitors. The Colosseum is also depicted on the Italian version of the five-cent euro coin. The Colosseum's original Latin name was Amphitheatrum Flavium, often anglicized as Flavian Amphitheatre. The building was constructed by emperors of the Flavian dynasty, following the reign of Nero. This name is still used in modern English, but generally the structure is better known as the Colosseum. In antiquity, Romans may have referred to the Colosseum by the unofficial name Amphitheatrum Caesareum, but this name may have been strictly poetic as it was not exclusive to the Colosseum; Vespasian and Titus, builders of the Colosseum, also constructed an amphitheater of the same name in Puteoli. The name Colosseum is believed to be derived from a colossal statue of Nero that once stood nearby. This statue was later remodeled by Nero's successors into the likeness of Helios or Apollo, the sun god, by adding the appropriate solar crown. Nero's head was also replaced several times with the heads of succeeding emperors. Despite its pagan links, the statue remained standing well into the medieval era and was credited with magical powers. It came to be seen as an iconic symbol of the permanence of Rome. In the 8th century, an epigram attributed to the Venerable Bede celebrated the symbolic significance of the statue in a prophecy that is variously quoted: Quamdiu stat Colisaeus, stat et Roma; quando cadet colisaeus, cadet et Roma; quando cadet Roma, cadet et mundus. This is often mistranslated to refer to the Colosseum rather than the Colossus. However, at the time that the Pseudo-Bede wrote, the masculine noun coliseus was applied to the statue rather than to what was still known as the Flavian amphitheatre. The Colossus did eventually fall, possibly being pulled down to reuse its bronze. By the year 1000 the name Colosseum had been coined to refer to the amphitheatre from the nearby Colossus Solis. The statue itself was largely forgotten and only its base survives, situated between the Colosseum and the nearby Temple of Venus and Roma. The name further evolved to Coliseum during the Middle Ages. In Italy, the amphitheatre is still known as il Colosseo, and other Romance languages have come to use similar forms such as Coloseumul, le Colisee, el Coliseo and o Coliseu. The site chosen was a flat area on the floor of a low valley between the Caelian, Esquiline and Palatine Hills, through which a canalised stream ran as well as an artificial lake/marsh. By the 2nd century BC the area was densely inhabited. It was devastated by the Great Fire of Rome in 64 AD, following which Nero seized much of the area to add to his personal domain. He built the grandiose Domus Aurea on the site, in front of which he created an artificial lake surrounded by pavilions, gardens and porticoes.
