The parish church has a very unusual tower which was originally 50 feet high and was built in the 14th/15th centuries. The upper part was brought down by explosives in the 1880s, but it was not properly capped until 1956 and now stands 24 feet high. The English poet, Sir John Betjeman mentioned the church in his poem "Summoned by Bells" (1960), chapter VIII.
