The Castra Albana [ˈkastra alˈbaːna] was an ancient Roman legionary fortress of the Legio II Parthica founded by the Emperor Septimius Severus (193–211) on the site of the present Albano Laziale.
It was the only permanent legionary fortress in Italy and had the role of protecting the emperor, while all other legions were distributed through the provinces for defence of the empire. It was located near to the imperial villa at the present Castel Gandolfo, and only about 20 km from Rome.
Today the remains of building both inside the castra and in the neighbouring civilian settlement, such as the so-called Baths of Caracalla and the Amphitheatre, can still be seen.
