Domus Transitoria is a very mysterious palace, about which much less is known than about other residences of Roman emperors. Other palaces of the Caesars: Domus Augustea, Domus Tiberiana, Domus Augustana, and Domus Flavia, Domus Severiana and even Domus Aurea) can still be admired on Palatine Hill or extensive ruins nearby. Meanwhile, surprisingly little is known about Nero’s first palace. Suetonius writes in the Lives of the Caesars that Nero built it to connect various residences inherited from his ancestors on the Palatine, Velia, Oppius and Esquiline. But this palace was destroyed during the great fire of Rome in 64 CE. Nero did not rebuild it, and on its ruins, he soon built Domus Aurea.
