For amateur architecture enthusiasts like me, this building is of significance. The main west window shown here, now sadly bricked up, was probably the first in England to contain bar tracery, moving from the simple lancet windows of the Early Gothic period to the more elaborate windows of the Decorated and Perpendicular Gothic periods. The window was built between in the early 1240s. It is thought that this window was used to test the technique before it was used in Westminster Abbey in 1245. Stone masons from Reims Cathedral in northern France, the first building anywhere to have bar tracery in its windows, advised the local stonemasons. After the Reformation the church fell into a poor state of repair and in 1809 the west window collapsed. Due to prevailing economic conditions at the time it was bricked up rather than rebuilt.
