Haselton (or Hazleton, Haseleton, Hasleton) lies high on the Cotswolds 14 kilometers SE of Cheltenham. The different spellings reflect variations in the local pronunciation of the name. The church, which is built of coursed, squared and dressed limestone, consists of a chancel, a nave with N aisle and S porch, and a W tower. The chancel and nave survive from the 12th-c church. In 1866 the church was extensively restored and enlarged by the addition of the two-bayed aisle, to designs by the firm of Medland, Maberly, and Medland. The Romanesque features comprise the S doorway, a corbel on the N side of the chancel, the chancel arch, and vault shafts in the chancel.

The manor of Haselton has its origins in an estate held before the Conquest by Goda (or Godgifu), sister of Edward the Confessor and wife of Eustace, count of Boulogne. Goda died in 1057, and in 1086 the estate belonged, together with estates in Yanworth and Hawling, to Sigar of Chocques. In the later 12thc the three estates, together with Sigar's estate at Gayton (Northants.), were held by the lords of Bethune, his descendants. William of Bethune granted the three Gloucestershire estates to Winchcombe Abbey c. 1201.
