Excavation in 1979 found an early building of two cells which was interpreted as pre-Conquest, as well as the foundations of the 12thc chapel. A stone reused in the footings of the medieval chapel has been suggested as being an early grave-marker (WYAS), but no safe definition can be made either of function or date, according to Coatsworth 2008, 283-4; ills. 839-40.
In medieval times, Tong was a parochial chapel in the parish of 'Birstal' (Lawton 1842, 112; Ryder 1993, fig. 179). Parish status was granted in 1867 (Nightingale c. 2012).
The Domesday Book recors that 'Stainulf [of Sutton] had 4 carucates of land for geld, where 2 ploughs can be. Ilbert [de Lacy] has [it], as a waste, Tempore Regis Edwardii [in the Confessor's reign] it was worth 20s. Pasturable wood [land] half a league in length and half a league in breadth' (VCH II, 252). Faull & Moorhouse state that there are ‘few records of the vill’. The lord of Tong between c.1135-1159 was Assulf, which was followed by four successive lords called Richard de Tang (Farrer 1916, 389-90, note to charter 1766, of c. 1160-1202). Assulf is also believed to have supported the rebuilding of the church of Tong around 1140 on the site formerly occupied by the pre-Conquest building. However, the dedication of the medieval chapel/church is not known for certain: a documentary source mentioning a 'chapel of St James' is cited in Swann (1993, 119).
The present building replaced the medieval church in 1727; the rebuilding was funded by the Tempest family who had built Tong Hall in 1702 (Pevsner 1967, 138). As presently seen, the church lies in a corner of the Hall grounds, but it was there first, of course. The sites of an earlier manor house and hall are off Keeper Lane (Rathmell 1996, 7); the site of the house of any local lord before the Conquest has not been identified.
