Benchmark & 1GL Bolt - St Mary the Virgin - Wansford, Cambridgeshire - European Historic Survey Stones, Monuments and Benchmarks on Waymarking.com

Cut benchmark & 1GL Bolt on the north west corner of the church tower, St Mary the Virgin, Wansford.

"St Mary's has a nave with a two-bay N aisle without any windows and a S doorway under a porch. The square-ended chancel has a N vestry and organ chamber, and there is a W tower with a broach spire with two tiers of lucarnes. An 11thc. window in the W wall of the nave indicates an early date for the core building. The S doorway dates from the early 13thc., and the N arcade and tower are slightly later. The S porch is dated 1663, and at that date too the S nave wall was rebuilt. The clerestoreys to N and S were presumably added at that time too. At some point, probably in the 15thc., the chancel fell down, and the E nave wall was rebuilt without a chancel. Until the new chancel was built in 1902 on the old foundations, St Mary's was claimed to be the smallest parish church in England. Construction is of stone rubble and ashlar. The church boasts an exceptional font of the 1120s."
