This church has a single nave, a central tower (probably built over the original chancel) and a chancel with a vestry on its N side. The chancel, tower and N aisle were added to a simple two-cell building in the late 12thc. century. The N aisle has been demolished and the N wall rebuilt. The church was restored in 1868 and again in 1874.
In 1086 Iford, in the Rape of Lewes, was held by William of Warenne in lordship and had a church.
The W face of the arch is of one order, comprising engaged nook shafts with double-scallop capitals, imposts with a very shallow chamfer, and an arch with a single row of hyphenated chevron, and a plain roll, on the face. The E face of the arch is plain, but one springer (N) is carved with a roll.
