when was the colosseum in rome italy built
Colosseum The Colosseum or Coliseum (/kɒləˈsiːəm/ kol-ə-SEE-əm), also known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium; Italian: Anfiteatro Flavio [aŋfiteˈaːtro ˈflaːvjo] or Colosseo [kolosˈsɛːo]), is an oval amphitheatre in the centre of the city of Rome, Italy. Built of travertine, tuff, and brick-faced concrete,[1] it is the largest amphitheatre ever built. The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in AD 72,[2] and was completed in AD 80 under his successor and heir Titus.[3] Further modifications were made during the reign of Domitian (81–96).[4] These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius).
Pantheon, Rome The Pantheon (/ˈpænθiən/ or US: /ˈpænθiɒn/;[1] Latin: Pantheum,[nb 1] from Greek Πάνθειον Pantheion, "[temple] of all the gods") is a former Roman temple, now a church, in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). The present building was completed by the emperor Hadrian and probably dedicated about 126 AD. He retained Agrippa's original inscription, which has caused confusion over its date of construction as the original Pantheon burned down, so it is not certain when the present one was built.[2]
Roman concrete It is uncertain when Roman concrete was developed, but it was clearly in widespread and customary use from about 150 BC; some scholars believe it was developed a century before that.[3]

It was completed by the emperor Hadrian and probably dedicated about 126 AD. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain the inscription of Agrippa's older temple, which had burned down.[2]
