St Mary's is famous above all for the Spencer Chapel, 'one of the great storehouses of costly and self-confident monuments of the 16thc., 17thc. and 18thc.' (Pevsner). This is the N chancel chapel, and was added by Sir John Spencer (d.1522) whose tomb is the earliest contained there, and who also rebuilt the chancel. The outer wall of the chapel, with a polygonal apse facing N, was rebuilt by Blore in 1846. The nave is six bays long with N and S aisles and clerestoreys. Both arcades are 14thc., but the N, lower and with plain chamfered arches, is apparently earlier than the S which has hollow chamfers. The west tower is 13thc. with a later battlement. The body of the church is of roughly course stone, and the eastern arm and Spencer Chapel of ashlar. The only feature described here is the Purbeck font, and that is probably 13thc. but included since it relates to a standard 12thc. type.

The Domesday Survey does not distinguish between Great and Little Brington, but describes the two holdings. William Peverel held 1½ hides, and William (the same or another) held half a hide from the Count of Mortain. No church was recorded in either parcel.
