The church of St Peter lies in rural surroundings near the junction of Church Lane, Kirkgate Lane and Slack Lane in what is now South Hiendley; Felkirk as a settlement appears to be losing or to have lost its separate identity. The church comprises nave, chancel with flanking chapels, north and south aisles and a west tower. In the churchyard there is also an Elizabethan schoolroom now converted into a church hall.
The church is mostly 15thc and 16thc but incorporates a large number of reused 12thc architectural fragments. These include the jambs of the present tower arch (Ryder 1991, 24) and a reset windowhead. There is herringbone walling in situ (Ryder 1991, fig. 34) on SE angle of the nave. The interior walls have been heavily retooled, probably during that restoration. A faculty of 1875 gives a plan of the church (Borthwick Institute York Fac. 1875/3)
The tower arch, to the level of the imposts, is early 12thc and incorporates some carving.
