Carlisle: Function and Change between the First and Seventh Centuries AD.

Archaeological excavations combined with antiquarian observations shed considerable light on the evolution of Roman Carlisle. From being a fort in the northern advance under Cerialis and Agricola, Carlisle developed as a nodal hub supported by a number of activity 'zones'. By the early third century most had become absorbed into the newly created civitas capital. The Roman town declined and stone buildings became ruinous, a process that probably commenced before the fourth century and continued until the land was taken over by the kings of Northumbria and the church in the seventh century. Scanty archaeological records for the sub- and post-Roman periods are supplemented by implications for socio-political structures drawn from texts. [ABSTRACT FROM AUTHOR]
