Cambridge
Cambridge was from its beginning a strategic centre and military base. Its castle, built later by the Normans on the outskirts of the town, remained a notable fortress and occasional royal residence until the late 13th century; thereafter it was used as a gaol and administrative centre for the shire as a whole, for Cambridge had by then been the county town for over 300 years. By our period Cambridge had long been one of the major market towns of the eastern counties, owing its economic importance largely to its geographical position.
