The manorial hamlet of Great Elm lies at about 100m OD on the L bank of Mells Stream just several kilometres downstream from Mells, among the hills of the E Mendips as they decline to the E. Less dominated than is Mells by limestone aggregate quarries because at their E limit, Great Elm occupies the N side of the Mells Stream valley just W of the large town of Frome. The church, which is built of random rubble, consists of a W tower, a nave with a S porch, a N transept and a chancel. Romanesque features recorded here are the blocked Norman doorway, partly obscured by the N transept, and the font.
