Wellington Square is the last remaining Georgian square in Cork (credit: Bishopstown, Wilton and Glasheen by Richard Henchion ISBN 0-9541293-0-X). The houses are listed as protected structures in the National Inventory of Architectural Heritage, with the following commentary:
The magazine was substantially remodelled in the first decades of the nineteenth century as housing for army officers and additional housing was constructed on the site at the time. Its historical associations, pleasing square-plan layout and architectural styles make this an interest group. Many important features and materials such as timber sash windows, limestone sills and thresholds and timber doors and surrounds are retained. The doors mirror those of the houses opposite, adding a sense of continuity to the square.
