Castra Praetoria, Ancient Roman military complex in Viminale Hill, Italy
The Castra Praetoria stands as a rectangular fortress with dimensions of 440 meters by 380 meters, covering an area of 17 hectares north of Rome.
Lucius Aelius Sejanus constructed these barracks in 23 AD under Emperor Tiberius to centralize the Praetorian Guard divisions within a single permanent structure.
The barracks represented the physical center of Roman military power, where emperors received proclamations and the Praetorian Guard conducted their duties.
Three of the original walls remain integrated into the Aurelian Walls, with visible sections near Rome Termini railway station at 70 meters above sea level.
In 193 AD, the Praetorian Guard conducted an auction within these walls to sell the position of Roman Emperor to the highest bidder.
