Fawley is a village on the W bank of Sothampton Water where it runs into the Solent; a position now dominated by the Esso oil refinery immediately W of the church. All Saints has a nave with 4-bay aisles, but the E bay of the S aisle is occupied by the arches of the tower. The chancel has a two-bay N chapel, used for weekday services, and a similar S chapel screened off for use as a vestry. The nave is 12thc in origin, with a chevron-decorated W doorway under a neo-Romanesque porch. The chancel arch, chancel chapel arcades and the W and N arches of the tower are 12thc work too (the E arch to the vestry is narrow and 19thc, and there is no S arch because the outer wall is in that position). The nave arcades are 13thc .

2 hides in Fawley were held by the Bishop of Winchester before the Conquest, but by 1086 only 1 virgate remained (with a chapel), the other 7 virgates having been taken into the New Forest. The church remained with the bishop, and had its own chapels at Exbury and Langley.

Pevsner and Lloyd (1967) date the S chancel arcade to the early 14thc, but they also give it three bays rather than two. The present author prefers the c.1200 date suggested by VCH. Otherwise Pevsner suggests a date of c.1170-80 for all of the Romanesque work except the chancel arch, which he dates ‘slightly earlier’.
