Glentworth is a small village in the West Lindsey district of Lincolnshire, 8 mile E of Gainsborough and 11 miles N of Lincoln. The church stands in the centre of the village; a building of coursed ironstone and limestone rubble, and ironstone and limestone ashlar. It consists of a W tower with a NW lean-to, and a nave and chancel in one with a S porch. The tower is late-11thc and of rubble with long-and-short quoins and bell-openings with volute tau-cross capitals. The nave dates from 1782 and, the chancel was rebuilt in the late 16th century, but has a reset 12thc. S doorway.

The king held 6 carucates of ploughland as sokeland of the manor of Kirton in Lindsey in 1086. A second holding of 7 bovates was held by Aestan in 1066 and by Wadard from Odo, Bishop of Bayeux in 1086. A third holding of 7 bovates was held by Godric before the Conquest and by Ansketil from Joscelin Fitzlambert in 1086. A holding of 6 bovates of land was held by Gamal in 1066 and by Martin in 1086, and a final holding of 7 bovates was held by Soti before the Conquest and Restold in 1086.

Pevsner suggests that the chancel arch is late 12thc., but the entirely plaster capitals suggest that it dates to the 1782 rebuilding.
