Colosseum in Rome,Italy (By : Kezia)

The Colosseum, or the Coliseum, originally the Amphitheatrum Flavium (English: Flavian Amphitheatre, Italian: Anfiteatro Flavio or Colosseo), the largest amphitheatre in the world, is an elliptical amphitheatre in the centre of the city of Rome, Italy, the largest ever built in the Roman Empire, built of concrete and stone. It is considered one of the greatest works of Roman architecture and Roman engineering.

Occupying a site just east of the Roman Forum, its construction started in 70 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).

Capable of seating 50,000 spectators, the Colosseum 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. Unlike earlier Greek theatres that were built into hillsides, the Colosseum is an entirely free-standing structure. It derives its basic exterior and interior architecture from that of two Roman theatres back to back. It is elliptical in plan and is 189 meters long, and 156 meters wide, with a base area of 24,000 m2. The height of the outer wall is 48 meters. The perimeter originally measured 545 meters. The central arena is an oval 87 m long and 55 m wide, surrounded by a wall 5 m high, above which rose tiers of seating.

Although in the 21st century it stays partially ruined because of damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome. It is one of Rome's most popular tourist attractions and still has close connections with 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. The Colosseum is also depicted on the Italian version of the five-cent euro coin.

Use

The Colosseum was used to host gladiatorial shows as well as a variety of other events. The shows, called munera, were always given by private individuals rather than the state. They had a strong religious element but were also demonstrations of power and family prestige, and were immensely popular with the population. Another popular type of show was the animal hunt, or venatio. This utilized a great variety of wild beasts, mainly imported from Africa and the Middle East, and included creatures such as rhinoceros, hippopotamuses, elephants, giraffes, aurochs, wisents, Barbary lions, panthers, leopards, bears, Caspian tigers, crocodiles and ostriches. Battles and hunts were often staged amid elaborate sets with movable trees and buildings. Such events were occasionally on a huge scale; Trajan is said to have celebrated his victories in Dacia in 107 with contests involving 11,000 animals and 10,000 gladiators over the course of 123 days.

During the early days of the Colosseum, ancient writers recorded that the building was used for naumachiae (more properly known as navalia proelia) or simulated sea battles. Accounts of the inaugural games held by Titus in AD 80 describe it being filled with water for a display of specially trained swimming horses and bulls. There is also an account of a re-enactment of a famous sea battle between the Corcyrean (Corfiot) Greeks and the Corinthians. This has been the subject of some debate among historians; although providing the water would not have been a problem, it is unclear how the arena could have been waterproofed, nor would there have been enough space in the arena for the warships to move around. It has been suggested that the reports either have the location wrong, or that the Colosseum originally featured a wide floodable channel down its central axis (which would later have been replaced by the hypogeum).

Sylvae or recreations of natural scenes were also held in the arena. Painters, technicians and architects would construct a simulation of a forest with real trees and bushes planted in the arena's floor, and animals would then be introduced. Such scenes might be used simply to display a natural environment for the urban population, or could otherwise be used as the backdrop for hunts or dramas depicting episodes from mythology. They were also occasionally used for executions in which the hero of the story – played by a condemned person – was killed in one of various gruesome but mythologically authentic ways, such as being mauled by beasts or burned to death.
