Thomas Hancorne, a jacobite prominent in High Church circles, was rector of St Donat's from 1674 to 1707.

[1] Originally built in the 12th century, St Donat's retains architectural features from all five of its different stages of growth.

[4] The chancel was reconstructed in the 15th century with many features from that build still in evidence: the piscina (altar basin) with cusped ogee hood, the nave with its north porch, the corbelled parapets to the nave with gargoyles and the corbelled tower battlements.

Other features of note include the circular font with roll top and bottom with scale patterned sides.

[4] The eastern window is of stained glass and displays an image of Saint Donat (circa 1862), believed to be by Clayton and Bell, but its providence is uncertain.

[6] A memorial cross to Mary Anne Nicholl-Carne, a former owner of St Donats Castle who died in 1879, has grade II listed status and is found to the north west of the church tower.
