This is the site of the medieval church of St John's. It was originally built in the 11th or early 12th century. William Cumyn fortified it in 1143-4, when the chancel was probably destroyed. The church was dismantled and rebuilt in 1850, though the Norman arches were built into the 19th century fabric.

Norman church, rebuilt 1850-1, incorporating part of the original north wall. Plan comprises nave, central tower, north transept and chancel. Built of sandstone rubble with slate roofs. In 1143, the church was used as a fortress by a usurping Bishop, William Comyn, who had a defensive ditch dug around it. During World War II the tower was used as an observation post against enemy bombers.
