The arcade leading to the North Aisle is the oldest part of the building as it exists today. The pointed Gothic arches with the circular, Norman column headed by a square foliated capital. The north aisle itself was considerable altered in the 18th century, and the windows were added at the time, although on to the west, has been replaced since. In the east wall, however, is a 15th century, square headed window, originally with two cinquefoiled lights, from which mullion, with the cusping above it has been removed.
