The east and west walls are divided into three bays by flat buttresses and the south wall into seven. The east wall contains a large window with gothic tracery above the chancel, measuring wide by high, and is flanked by a smaller window on each side. At each corner of the structure is an octagonal buttress. The buttresses on the east wall were originally capped by small stone spires and a cross capped the peak of the gable above the chancel window. The west wall contains a diameter rose window, above which was a small bell tower.
