Houghton Conquest's rectory was united with that of Houghton-Gildable in 1637, in the archdeaconry of Bedford, and diocese of Lincoln.
[3] The church is spacious, built in the Early English Period and Decorated styles.
It consists of chancel, nave, aisles, south porch, and an embattled tower containing six bells.
The stained-glass east window, erected in 1880 by John William Burgon, Dean of Chichester, is a memorial to three benefactors.
Built in 1830, some of the walls bear traces of frescoes, the designs of which are in some parts sufficiently distinct to be distinguished.
