Excerpt: …church, of seven bays. The nave of Norham is of five bays. Melbourne has five bays, but the plan of the church was as exceptional at the west as at the east end. Western towers were planned, but not completed, at the end of either aisle: this feature, probably imitated from Southwell minster, was also contemplated at Bakewell in Derbyshire. Between the towers was an extra western bay of the nave, divided into two stories, the lower forming a vaulted return aisle, the upper forming a gallery. There are only four bays at Sherburn, but here the aisles were continued as far as the western face of the tower. The tower is thus engaged within the aisles, and its vaulted ground floor forms, like the western bay at Melbourne, a return to them.
