The nave probably incorporates part of the walling of a 12th century church to which aisles were added about the middle of the 13th century. The chancel arch was rebuilt in the first half of the 14th century, but by the middle of the century the condition of the fabric must have become very unsatisfactory, as its restoration was undertaken by John Olney, lord of the manor, about 1368, in which year the church was refounded. The rebuilding of the chancel was probably the only work accomplished by this date, but the reconstruction of the rest of the building appears to have been continued during the next twenty years, the nave arcades being rebuilt, largely with the old material, the clearstory added, and new windows inserted in both aisles. The tower and north porch were added about the middle of the 15th century. The church was restored in 1891.

Nailed to the modern boarded floor of the chancel is an inscription on strips of brass to John Olney, kt., and his wife Denise, 1395. The inscription is in Latin but very defective, and the strips are fixed in the wrong order. At the four corners are the symbols of the Evangelists. There were probably brass figures within the inscription, but they have disappeared, and the only remaining portion is a brass shield bearing an embattled fesse. At the east end of the floor of the south aisle is the brass figure of a lady in an embroidered gown with slashed sleeves, the head missing; beneath is an inscription to Elizabeth (d. 1553) daughter of Lord Hussey, wife of (I) Walter Lord Hungerford, and (2) Robert Throckmorton. There are also a group of five daughters and four shields of arms: (I) Throckmorton; (2) Hussey; (3) Throckmorton with six quarterings impaling Hussey and Fortescue; (4) Hungerford impaling Hussey; and the indent for a fifth shield now missing. On the east wall of the same aisle is a large monument of marble to (I) Thomas Throckmorton, 1614; (2) Sir Francis Throckmorton, kt. and bart., 1680; (3) Francis son of the last (d. at Bruges, his heart buried here, 1676); (4) Robert son of Sir Robert Throckmorton, bart., 1688; (5) Sir George Throckmorton, bart., 1826; and (6) his wife Catherine, 1839. In the same aisle are mural tablets to members of the Higgins, Chapman and Ruck families, 1726 to 1819; in the north aisle are three Higgins tablets, 1792 to 1802, and a floor slab to Dorothy wife of John Frasie, 1709. In the north porch are two slabs to Ann Butcher, 1729, and Mary wife of Charles Bennet, 17-. In the chancel is a tablet to the Rev. John Buchanan, friend of the poet Cowper (d. 1826).
