The current building is of cruciform shape, now mainly of perpendicular architecture, but still preserving in its south and west doorways, and in the tracery of some of its windows, marks of earlier styles.

The oldest, virtually untouched, part is the north transept, although it has now been transformed into a chapel as a war memorial.

The tower is supported by four massive arches and the nave and aisles are separated by arcades of five bays.

In the north transept is an incised slab to Henry Smyth (d 1496) and Sir Whatton Amcotts (d 1807) by William Kinnard, architect.

The Victorian stained glass includes work by Clayton and Bell, Charles Eamer Kempe, Michael O’Connor, Hardman & Co, William Wailes and George Shaw.

[2] The British Museum contains several architectural drawings of East Retford Church by Samuel Hieronymous Grimm.

John Buckler (1770–1851) made several drawings of the church, including one of the figure in the vesica piscis, at the beginning of the nineteenth century.
