St Margaret's has a large, squarish nave of alternate limestone and ironstone courses, dating from the rebuilding of 1827-28 by Charles Squirhill. This replaced an aisled C13th. nave, and the W responds of the arcades still remain, along with the S doorway under a medieval porch. Also from the medieval church are the small, square chancel (C13th.) and the W tower (C13th. in its lowest parts). There are vestries to N and S of the chancel, the S a modern addition. Inside the nave the church retains its W gallery, with an organ in the centre and benches to either side. The font may, at a pinch, be C12th, but is more probably C13th.

 

In 1086 Denton was divided between Countess Judith and Ramsey Abbey. No church was recorded.
