Leigh-on-Mendip is about 5 miles from Frome and Shepton Mallet. At about 200m OD up on the E Mendips, the large linear village occupies reasonably level land on a broad W-E ridge to the SW of the large limestone quarry of Halecombe. Disused quarries lie to the N and S, the latter adjacent to Downhead; indeed, the surrounding area is punctuated by them. 500m S of the village runs the old main road between Wells and Frome. The church was rebuilt c1500 but contains a Romanesque font.

The manor is not mentioned in DB; it formed part of Glastonbury Abbey's estate of Mells until the dissolution (Viggiani).

This is one of many Somerset churches rebuilt in the later medieval period which preserves an early font.
