The Palace of Domitian was built as Roman emperor Domitian's official residence in 81–87 AD and was used as such by subsequent emperors. Its remains sit atop and dominate Palatine Hill in Rome, alongside other palaces. The Palace is a massive structure separated today into three areas. In the past, these partitions allowed business and political matters to have separation from private life while their close proximity allowed them to be conducted in parallel if required. The modern names used for these areas are: the Domus Flavia the Domus Augustana the garden or "stadium". Not all of the palace can be seen as portions lie under more recent buildings, much like a significant portion of the remains of Ancient Rome. The palace was one of Domitian's many architectural projects including renovation of the Circus Maximus, renovation of the Pantheon, and three temples deifying his family members: the temple of Vespasian and Titus, the Porticus Diuorum, and the Temple of the gens Flavia.
