Construction, inauguration, and Roman renovations of Titus celebrating the inauguration of the Colosseum (minted 80 AD). 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. The existing
Aqua Claudia aqueduct was extended to supply water to the area and the gigantic bronze
Colossus of Nero was set up nearby at the entrance to the Domus Aurea. Although the Colossus was preserved, much of the Domus Aurea was torn down. The lake was filled in and the land reused as the location for the new Flavian Amphitheatre. Gladiatorial schools and other support buildings were constructed nearby within the former grounds of the Domus Aurea. Vespasian's decision to build the Colosseum on the site of Nero's lake can be seen as a populist gesture of returning to the people an area of the city which Nero had appropriated for his own use. In contrast to many other amphitheatres, which were on the outskirts of a city, the Colosseum was constructed in the city centre, in effect, placing it both symbolically and geographically at the heart of Rome. '' (1904) Construction was funded by the opulent spoils taken from the
Jewish Temple after the
First Jewish–Roman War in 70 AD led to the
Siege of Jerusalem. According to a reconstructed inscription found on the site, "the emperor
Vespasian ordered this new amphitheatre to be erected from his general's share of the booty." It is often assumed, as it is with many other Roman projects at the time, that slaves and prisoners of war were brought back to Rome and contributed to the massive workforce needed for the construction of the amphitheater. Along with this free source of unskilled labor, teams of professional Roman builders, engineers, artists, painters and decorators undertook the more specialized tasks necessary for building the Colosseum. The Colosseum was constructed with several different materials: wood, limestone,
tuff, tiles, cement, and mortar. Construction of the Colosseum began under the rule of Vespasian
Dio Cassius recounts that over 9,000 wild animals were killed during the
inaugural games of the amphitheatre. Commemorative coinage was issued celebrating the inauguration. The building was remodelled further under Vespasian's younger son, the newly designated Emperor
Domitian, who constructed the
hypogeum, a series of tunnels used to house animals and slaves. He also added a gallery to the top of the Colosseum to increase its
seating capacity. In 217, the Colosseum was badly damaged by a major fire (caused by lightning, according to Dio Cassius), which destroyed the wooden upper levels of the amphitheatre's interior. It was not fully repaired until about 240 and underwent further repairs in 250 or 252 and again in 320.
Honorius banned the practice of gladiator fights in 399 and again in 404. Gladiatorial fights are last mentioned around 435. and 508. The arena continued to be used for contests well into the 6th century. Animal hunts continued until at least 523, when
Anicius Maximus celebrated his consulship with some
venationes, criticised by King
Theodoric the Great for their high cost. Severe damage was inflicted on the Colosseum by the great
earthquake in 1349, causing the outer south side, lying on a less stable
alluvial terrain, to collapse. Much of the tumbled stone was reused to build palaces, churches, hospitals and other buildings elsewhere in Rome. In 1377, after the Pope's return to Rome, the Colosseum was restored by a religious order called Arciconfraternita del SS. Salvatore ad Sancta Sanctorum, who then inhabited a northern portion of it until as late as the early 19th century. The interior of the amphitheater was extensively stripped of stone, which was reused elsewhere, or (in the case of the marble façade) was burned to make
quicklime. In 1671, Cardinal
Paluzzo Altieri authorized its use for
bullfights; a public outcry caused the idea to be hastily abandoned. In 1749,
Pope Benedict XIV endorsed the view that the Colosseum was a sacred site where early Christians had been
martyred. He forbade the use of the Colosseum as a quarry and consecrated the building to the
Passion of Christ and installed
Stations of the Cross, declaring it sanctified by the blood of the
Christian martyrs who perished there (
see Significance in Christianity). However, there is no historical evidence to support Benedict's claim, nor is there even any evidence that anyone before the 16th century suggested this might be the case; the
Catholic Encyclopedia concludes that there are no historical grounds for the supposition, other than the reasonably plausible conjecture that some of the many martyrs may well have been Christian. , showing the
Stations of the Cross around the arena and the extensive vegetation Later popes initiated various stabilization and restoration projects, removing the extensive vegetation which had overgrown the structure and threatened to damage it further. The façade was reinforced with triangular brick wedges in 1807 and 1827, and the interior was repaired in 1831, 1846 and in the 1930s. The arena substructure was partly excavated in 1810–1814 and 1874 and was fully exposed under
Benito Mussolini in the 1930s. or if a jurisdiction abolishes the death penalty. Most recently, the Colosseum was illuminated in gold in November 2012 following the abolishment of capital punishment in the American state of
Connecticut in April 2012. Because of the ruined state of the interior, it is impractical to use the Colosseum to host large events; only a few hundred spectators can be accommodated in temporary seating. However, much larger concerts have been held just outside, using the Colosseum as a backdrop. Performers who have played at the Colosseum in recent years have included
Ray Charles (May 2002),
Paul McCartney (May 2003),
Elton John (September 2005), and
Billy Joel (July 2006). == Physical description ==
