In 1826 an ornate range was erected by St Mary Hall in the Gothic Revival style, incorporating the old gate of St Mary Hall, on the west side of the quad. Designed by Daniel Robertson, it contains two quite ornate oriels placed asymmetrically, one is of six lights, the other four. They are the best example of the pre-archaeological Gothic in Oxford. The large oriel on the first floor at the north end was once the drawing room window of the Principal of the Hall. Parts of the street wall incorporated into this range show traces of blocked windows dating from the same period of rebuilding in the 15th century as the present-day staircase ten.
