St Margarets is in the SW of the county, 10 miles SW of Hereford, between the Golden Valley to the E and the Black Mountains to the W. The church stands alongside Tanhouse farm in an otherwise secluded position. It consists of a chancel and nave with a SW porch and a weatherboarded W bell turret capped by a pyramid roof. The chancel arch is 12thc (the only feature recorded here) and other diagnostic features are late medieval at the earliest. The church was restored by E. H. Lingen Barker in 1901-02, and the porch is of 1924. The most spectacular and surprising feature is a wooden rood screen with loft, carved with finely executed foliage ornament and dateable to c.1500.

St Margarets is not recorded in the Domesday Survey, but according to Duncumb (1812) it was part of the great manor of Ewyas Lacy. Until the 11thc this was part of Wales, but attempts by Edward the Confessor to bring it under English control left it a disputed area at the Conquest, nominally under the overlordship of Walter de Laci to whom it was given by William I.

The church was appropriated to the Abbot and convent of Llanthony.
