The Blackadder Aisle at Glasgow Cathedral: a reconsideration of the architectural evidence for its date

Abstract

It is argued from analysis of the mouldings and other features that the Blackadder Aisle was built in two stages, separated by at least two centuries. The shell of the lower storey may be the work of the same mason who built the choir in the mid 13th century, while Archbishop Blackadder (1483-1508) merely covered the incomplete shell with its vault, albeit sympathetically blended in.
