In Chester (northern England) there are remains (walls and towers) of the Roman military camp Deva Victrix, which was founded around 70 CE. It was built by Legion II Adiutrix.
It is believed that the name of the camp derives from the deity of the river Dee and the name of the legion, which then stationed here – the Legion XX Valeria Victrix.
The fort controlled the bridge over the Dee River and had a typical rectangular shape with rounded corners. The camp (covering 25 ha) was surrounded by a 2-meter wide ditch. It was the largest military complex in Britain. The fort had barracks, granaries, workshops, bathhouse and headquarters – principia.
After 80 CE there was an expansion of the fort, which received massive walls, and a settlement began to shape around the camp, which over time had i.e. amphitheatre.
