|Italian archaeologists have found the remains of a barracks that they believe may have been used by ancient Rome's equivalent of the secret service. The discovery was made during deep excavations for a new metro station in Rome. The barracks, which include a dormitory for legionaries, were part of a huge imperial military complex that was built during the reign of the Emperor Hadrian.|
The complex included cavalry barracks, which now lie beneath the Basilica of St John Lateran.
|The emperor's spies were known in Latin as "frumentarii". They were originally tasked with provisioning the army with supplies. Under Emperor Hadrian, they developed into a network feeding information back to Rome.|
The barracks were abandoned and built over when high protective walls were built around the city by the Emperor Aurelian in the late third century AD.
