The camps were part of Rome’s 200-year conquest of what it called Hispania.
The scientists found the camps using sensors, online mapping tools, and drones.
Archaeologists have discovered the remains of dozens of Roman military camps in northern Spain, ferreting out their location thousands of years later. The scientists discovered the camps, set by Roman legions during the pacification of Hispania, using a combination of online maps, satellite photography, lidar, and drones.
One of the oldest features of military life is the armed camp. Armies on the move must prepare positions to spend the night, take shelter from the elements, or train. In antiquity and even today armies typically have exacting procedures for setting temporary quarters.
