The two pre-Conquest manors of Wickham were unified by Hugh de Port, who was granted the property by William I. No church was mentioned in 1086. According to the guidebook, ‘documents from the episcopate of Henry de Blois (1129-1171) show that the church was dedicated to St. Nicholas and granted parochial rights and status’ (Retallack 2022, 14). The mid-12thc W doorway is the earliest datable feature of the building.
The 12thc church probably comprised a simple nave and chancel. As a result of extensive 19thc rebuilding, the original dates of the S chapel (variously a chapel or vestry; since 1961 the Lady Chapel) and the N and S transepts are unclear. The S transept has been variously dated to the 17thc (Retallack 2022, 15) and to 1803 (VCH 1908, 235). The latter date is supported by a guide of 1801, cited by Retallack, which mentions just one addition on the S side of the church, presumably the S chapel (Retallack 2022, 15). The same source confirms that the 12thc doorway (though described as ‘Saxon’) was located at the W end of the nave.
Two views of the church pre-dating restoration work of 1861-62 show that a timber bell turret with a pyramidal roof occupied the W end of the nave, and that the W doorway was protected by a porch (Retallack 2022, 15-16). Another early view, a watercolour by R. H. C. Ubsdell dated 1841, shows a vestry with a chimney stack on the N side of the chancel.
The work of 1861-62, by the London architects F. & H. Francis, has been described as ‘virtual rebuilding’ (HE List Description). It was certainly extensive, but did not amount to a complete rebuilding. The bell turret was replaced by a W tower and the W doorway was relocated. The N transept was rebuilt (Builder, 12 April 1862, 265). The chapel or vestry on the S side of the chancel was largely reworked. At a later date, probably in the 1870s, an organ chamber was built on its W side, abutting the S transept. The organ was bought in 1880 (Hampshire Telegraph, 6 January 1933, 12).
The church room of 1974 was designed by Potter & Hare, who had refurbished the interior in the 1960s (Pevsner & Lloyd 1967, 652).
