For over 100 years, archaeologists have been stydying Roman Carnuntum, on the Danube River near Vienna, but only recently were they aware of the existence of a ludus, or gladiator school, covering 30,138 square feet (2,800 square meters). The new research has been used to construct a 3D model of the site. (photos)
Instead of excavations, experts used emote-sensing techniques which helped locate the remains of the building. The site would have included a cell blocks, a training arena and a bath complex. "The most prominent feature inside the courtyard is a free-standing circular structure 19 m [62 feet] in diameter, which could be interpreted as the training arena for the gladiators," the authors write in the journal Antiquity. "This might be the foundation of the palus, a wooden pole used for exercising blows with the sword and body slams with the shield."
