The church has a unique quintuple Norman Chancel arch probably built between 1130 and 1170 and has remained untouched. The rare sexpartite vaulting in the little chancel hardly existed elsewhere in Romanesque work until William of Sens imported it to Canterbury Cathedral in 1175 and later copied in Lincoln Minster. It was rebuilt by Eliza Winfield from designs by S. P. Cockerell in imitation of the original work, together with the western part of the church in a Late 18th century version of Norman architecture.
