Spy Photographs

Archaeologists in Britain have discovered what appears to be a series of Roman fortifications dating back to the 2 nd century AD by examining declassified spy photos taken during World Wars I and II, as well as images made by American spy satellites during the Cold War. The entire structure ran about 37 miles across modern-day Romania from the Danube River to the Black Sea. In some parts, the system of walls and forts may have once stood 28 feet wide and more than 11 feet high. The discovery reveals that the Roman conquest of the region was far more elaborate than originally thought and indicates that the area had been heavily militarized and carefully controlled during the Roman period
