Evidence of pagan and Christian worship has been discovered. Two altars have been found and there may be a temple of Mithras at the site. A word square was discovered in the 1970s that may be one of the earliest examples of Christianity in Britain. A civilian settlement ("") grew in association with the fort, made up of traders and the soldiers' families. An area which has a concentration of furnaces and industrial activity has been described as an industrial estate. The civilian settlement was probably abandoned by the mid-3rd century, although a small garrison may have remained at Mamucium into the late 3rd and early 4th centuries.
