St Mary's is a church of nave, chancel and W tower. The nave is aisled with three-bay arcades, the N late 12thc., the S 13thc. The roof has been heightened and there is a late medieval clerestorey. The chancel arch is 13thc. as is the chancel stylistically, but it was entirely rebuilt by Sir Henry Dryden in 1846. The tower is of three storeys, 13thc. except for the battlement. The N and S nave doorways are both under porches; the N doorway being contemporary with the N arcade and the N porch dated 1649. Construction is of stone rubble except for the clerestorey and the rebuilt chancel, both of ashlar. Romanesque features are the N doorway, N arcade and font.

Moreton Pinkney was held by Geoffrey from Giles, the brother of Ansculf in 1086. No church was recorded at that time, the earliest notice being in c.1150-75 when the Pinkney lords transferred it to Canons Ashby priory.

Benefice of Culworth with Sulgrave and Thorpe Mandeville and Chipping Warden with Edgcote and Moreton Pinkney.

The arcade capital forms and pointed arches suggest a date c.1200. The font and N doorway are not closely dateable.
