The church was rebuilt by A W Blomfield in 1885. None of the 12thc. sculpture that decorated its predecessor seems to survive.

In 1105 Robert de Haye (to whom Henry I had given the honor of Halnaker) gave the church of Hunston with its lands and tithes to the abbey of Lessay in Normandy. In 1187 his grandson, WIlliam de St John, confirmed this gift to Boxgrove Priory (a dependency of Lessay), but the manor seems to have been held in fee by a younger branch of Robert's family. Boxgrove held Hunston until the Dissolution. The chancel was rebuilt between 1719 and 1759, visited by Sir William Burrell in 1776 and drawn and described for Gentleman's Magazine in 1792. The church was wholly rebuilt in 1885.

In this area, the only loose chevron voussoirs lacking a provenance are in Bosham church.
