Turnastone is a hamlet in the Golden Valley, in the South Herefordshire district. It is 10 miles W of Hereford and the nearest village is Vowchurch, less than half a mile to the E. The church has an aisleless nave and chancel in one with a low weatherboarded timber bell turret with a pyramid roof over the W gable and a timber S porch. There is a 12thc breccia font, but the S nave doorway of c.1200 is the oldest dateable fabric. The church is of decoratively coursed roughly-shaped sandstone and shows signs of work c.1300 (nave windows) and c.1500 (chancel doorway). There was a restoration by T. Edgar Williams of London in 1884.

Neither Turnastone nor nearby Vowchurch is mentioned by name in the Domesday Survey. Marshall (1938) suggested that Turnastone was the unidentified Domesday manor of Edwardestune, held by Walter from Roger de Lacy in 1086 and assessed at 1 hide. In 1221 it was in the possession of William de Anesyia (Dansey), who held it from the Chandos lord of the Honour of Snodhill.

The doorway is dated late Norman by Pevsner (1963) who calls its imposts ‘illiterate moulded capitals’; a piece of whimsy discarded by Brooks (2012), who prefers c.1200 for its date. The font is one of eight in the county, dated c.1140-50 by Halsey (1987), although Zarnecki preferred a date in the third quarter of the 12thc and RCHME says 'probably 13th-century'.
