The garrison of the governor's guard (castra singularium) in Carnuntum
In August 2014, the garrison of the governor's guard was detected using ground-penetrating radar (GPR) and magnetics. Situated immediately west of the legionary fortress, the so-called castra singularium formed a part of a huge building complex, which was the administrative center of the Roman province. A massive wall enclosed this newly-discovered military garrison, which consisted of several barracks for soldiers, a central administrative complex and buildings dedicated to logistical purposes. The combination of the governor's palace and the garrison of his guard - in close vicinity to the legionary fortress and the campus, the military training area of the legionaries - make this discovery unique in the Roman world.
