The Arch of Constantine is a triumphal arch in Rome, situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge on October 28, 312.
The Arch of Titus is a 1st-century honorific arch located on the Via Sacra, Rome, just to the south-east of the Roman Forum. It was constructed in c. 82 AD by the Roman Emperor Domitian shortly after the death of his older brother Titus to commemorate Titus' victories, including the Siege of Jerusalem in 70 AD. The Arch of Titus has provided the general model for many of the triumphal arches erected since the 16th century—perhaps most famously it is the inspiration for the 1806 Arc de Triomphe in Paris, France, completed in 1836.
Construction of the Colosseum began under the emperor Vespasian in 70 AD, and was completed in 80 AD under his successor and heir, Titus. Further modifications were made during the reign of Domitian (81–96). The period of rule for these three emperors is known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius). The Colosseum could hold, it is estimated, between 50,000 and 80,000 spectators and 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.
