The Most Powerful and Notorious Address on Earth – Domus Augustana Part 1

Today, the Domus Augustana is one of the most impressive ruins on the Palatine Hill, but only a fraction of the palace remains standing. Perched atop Rome’s famous rise, the private residence of the emperors was one of the most powerful addresses in the ancient world. In 96 A.D. when my Secrets of Ephesus murder series takes place, Domus Augustana was the Heart of an Empire, and the palace would have looked vastly different than today. The first image reimagines what it could have looked like two thousand years ago.

From the Palatine Hill, emperors ruled with seemingly unlimited power; adopting the title of Principate instead of emperor or king, to enforce the illusion that they were not dictators. During the period from Augustus in 27 BC through the reign of Marcus Aurelius in AD 180—the emperor, supported by alliances within the army, the Senate, and the Praetorian Guard, was essentially untouchable. There was no legal impeachment, voting him out, or forcing him from office. If an emperor became egotistical, unstable, cruel, or simply unfit to rule, Rome had only two practical remedies: a military coup or assassination. As a result, the imperial throne was both the most powerful seat in the world and one of the most dangerous.

The palace Domus Augustana was the perfect setting for murder.

Thirty-seven emperors are documented as having been murdered—not including Nero, who died by suicide after the military turned against him. The palace’s vaulted chambers, stairways, and multi-level terraces descended the hillside, while subterranean rooms and passageways used by servants, guards, and maintenance workers still survive today. It offered countless hiding places for an assassin, escape routes for a guilty servant, or opportunities for a Praetorian bodyguard to abandon his post.

1. Nero – Suicide,  2. Caligula- assassinated, 3. Claudius – poisoned, 4. Galba – assassinated, 5. Domitian – assassinated.

As fascinating as the palace itself is, its most enduring legacy may be Domitian’s assassination that occurred within its walls—an event that launches Powers of Death, the third book in the Secrets of Ephesus series.
