Magnis

Magnae, sometimes Magnae Dobunnorum to distinguish it from the Magnae of the Carvetii on Hadrian's Wall in northern Britain, was a Romano-British town and an important market centre for the British Dobunni tribe, located near modern-day Kenchester in Herefordshire, England. The town was shaped as an irregular hexagon, with a single main street along the line of the main Roman Road running east–west through the area, and an irregular pattern of side streets with tightly packed buildings leading off it.
