Much Wenlock is located at the northwest end of Wenlock Edge in a valley. The site was within the precinct of Much Wenlock monastery until the early 12thc. The church was originally aisleless, but a S aisle was added in the 14thc. The nave dates mainly from the 12thc, as do parts of the chancel. The E window is 15thc. The chancel arch is much restored.
A blocked-up 12thc doorway, which is much renewed, exists on the N wall of the nave. It has two orders and is unornamented. The W front of the church, elaborately decorated with 12thc sculpture, was concealed by the addition of a W tower in the late 12thc. This W front consists of a doorway, above which a large window is surrounded by two rows of blind arcading, and above that a second smaller window likewise surrounded by blind arcading.
