Glevum (or, more formally, Colonia Nervia Glevensium, or occasionally Glouvia) was originally a Roman fort in Roman Britain that became a "colonia" of retired legionaries in AD 97. Today, it is known as Gloucester, 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.
