Final answer:
Notable Romans, including illustrious men and emperors, were traditionally buried outside the city walls of Rome, in accordance with their religious customs that prohibited burials within the city's sacred boundary. The Colosseum and Circus Maximus were venues for live entertainment, not burial sites.
Step-by-step explanation:
The Romans traditionally buried illustrious men and emperors outside the city walls. This practice was part of their belief system that considered burials within the sacred boundary of the city (the pomerium) to be taboo. The elaborate tombs and mausoleums built to commemorate these significant individuals were often constructed along prominent roads leading out of the city. Examples include the Mausoleum of Augustus and Hadrian's Mausoleum, known today as Castel Sant'Angelo, both of which were located outside the ancient city's boundaries.
While structures such as the Colosseum (Flavian Amphitheater) and the Circus Maximus were significant buildings in ancient Rome, they were not used for burial purposes but for public entertainment, such as gladiatorial matches, chariot races, and staged naval battles. The Colosseum, in particular, was a monumental arena where up to fifty thousand spectators watched games and shows designed to display imperial grandeur and distract the populace from potential governance issues.
It is clear that the burial of notable Romans was strictly an outside the city matter to abide by tradition and religious customs, ensuring a respectful distance between the living and the dead.
