Glevum (or, more formally, Colonia Nervia Glevensium, or occasionally Glouvia) was a Roman fort in Roman Britain that became a "colonia" of retired legionaries in AD 97. Today it is known as Gloucester, located in the English county of Gloucestershire. The name Glevum is taken by many present day businesses in the area and also by the 26-mile Glevum Way, a long-distance footpath or recreational walk encircling modern Gloucester.
