The Kenilworth Duchy of Lancaster lands (the 'Duchy Manor' or 'Castle Manor') were roughly the half of the town which is south of the present day clock tower in the Square, and this was known as 'Castle End'. The half of the town to the north was known as 'Abbey Manor' , the 'Augmentation Manor' or Abbey End. See http://www.british-history.ac.uk/report.aspx?compid=57113 which says: 'In 1581 each manor had a court leet and assize of bread, beer, and ale. The former manor in Castle End had 43 free tenants with 47 holdings, and 11 customary tenants with 12 holdings. A fair was held each year at Michaelmas. In the Abbey manor there were 5 free tenants with 6 holdings, 29 customary tenants with 31 holdings, and 1 tenant at will; a fair was held in the High Town at Midsummer even, Midsummer day, and the day after, where horses and cattle were sold.'
