Allexton is a village in the Harborough district of E Leicestershire, alongside the Eye Brook which forms the border with Rutland. It is 15 miles E of Leicester but the closest town of any size is Corby, 9 miles to the S. The village consists of the church and a few houses dispersed along the main street. The church as it stands today consists of an aisled nave, chancel with a N porch and a W tower. Following Pevsner's analysis, the N arcade was added to the nave c.1160 and the chancel arch c.1180. The nave was extended W by one bay and a S arcade added in the 14thc. In the 15thc, a W tower was added within the W bay of the nave, effectively blocking it off., so that when the aisle bays were removed at the W end, the blocked arches remained visible. In a restoration of 1862, the Norman N arcade was rebuilt retaining the old materials, but the chancel arch was replaced , keeping only the responds and their capitals. The aisles were also rebuilt in 1862, and dormers added. Construction is of coursed and rubble ironstone with limestone dressings. The only Romanesque features recorded here are the N arcade and the chancel arch.

The church was made redundant in March 2000 and was vested in the Churches Conservation Trust the following month.

In 1086, 5 carucates of ploughland were held by Grimbald from Judith, Countess of Huntingdon. Judith's overlordship had passed, by 1124-29, to David, king of Scots as Earl of Huntingdon. Robert Grimbald was hereditary possessor of the manor in the early 12thc, and Allexton was held from him by his brother in law, Robert de Bakepuiz. The Bakepuiz family (whose chief seat was at Barton Bakepuiz in Derbyshire), were the owners of Allexton in the Norman period and later, the church being under their patronage.

The N arcade has a cleaned-up look. Claw chisel marks are very visible on the vertical faces of capitals and columns.
They were probably scraped and retooled when reconstructed in 1862.
