Church consists of a W tower, nave with a four-bay arcade, N and S aisles, clerestory, and a chancel with N chapel. S doorway and tower arch are 13thc. while the nave arcade is 14thc.; the clerestory, upper part of tower, and the chancel are late medieval. C. H. Fowler did some restoration work here in 1891. The W doorway and W window of the tower, as well as the corbel table on the S porch, are Romanesque survivals.

There is no mention of Wigtoft in the Domesday Survey.

As suggested by Pevsner, the W tower doorway and window have likely been re-set from their original position in the W wall of the nave where the now blocked companion side windows of the W doorway can still be seen inside.
