This small church, approached through a farmyard in a tiny hamlet, has a single nave with opposing doorways (now corresponding to a porch on the S and a vestry on the N, both 19thc. additions), and a apsidal E end. The nave and apse are of the same height and are roofed together, with no structural demarcation of space. The Romanesque style apse windows are modern. There is no electricity.

North Marden may have been among the five fees held by Hugh de Falaise in the reign of Henry I, as his grand-daughter Agnes, widow of Geoffrey son of Azo, held a 1/3 fee there. The right of presentation went with the manor in the 13thc. and may also have done so in the 12thc. The church may originally have been chapel of ease to East Marden

The archivolt of North Marden is very similar to that of the Canon Lane doorway in Chichester. The Maltese cross at the apex of the label appears to be an insertion.
