The village is located in the Blackmore Vale in north Dorset and sits above the river Stour. The present building consists of a chancel rebuilt c.1882, a 14thc N chapel; a 15thc S chapel; a nave with a late-14thc N aisle; a S aisle and a porch of c.1852, and a 15thc W tower.
Marnhull is not mentioned in Domesday Book.
The Salisbury Diocesan registers of 1388-1413 record a chantry to St Mary at Marnhull, and the 14thc N chapel originally appears to have had a lodging for a chantry priest attached to its W wall.
