Before 1284 Edmund, Earl of Cornwall, gave the church of Wendron, with its chapels, to Rewley Abbey near Oxford. Before this it had belonged to the Earl's, Manor of Helston, which included the whole parish. The church is cruciform but was enlarged in the 15th-century and is a grade I listed building. The church contains the brass of Warin Penhalluryk, rector of St Just, vicar of Wendron and Stithians, d. 1535. The holy well of St Wendrona is at Trelill and nearby was her chapel, which was licensed in 1427, at about the same date as the well. At Degibna, on Loe Pool, was a chapel dedicated to St Degamanus. At Bodilly was a chapel of St Henry the Hermit (died 1120, feast day on 16 January). The Revd G. H. Doble served for almost twenty years as the vicar of Wendron (1925–1945).
