St. Medard’s has one of the most outstanding 12thc doorways of the county and is the only church in the country dedicated to this 6^th century saint. There is some Anglo-Saxon long-and-short work in the nave but the majority of the church is 12thc and 13thc. The lower section of W tower is 12thc, the bell-stage is 13thc, and the spire is 14thc/15thc Perpendicular. The 12thc nave has a three-bay S aisle of the early 13thc which goes along with the S porch. The chancel arch is 13thc but the rest of the chancel looks like 12thc masonry. The Romanesque work recorded here consists of the window and Priest’s doorway in the chancel, the N doorway of the nave, and the W tower arch.

A village of “Bytham” is mentioned in Domesday Book but there is no reference to a church here in 1086. However, the long-and-short work on the nave quoins point to an Anglo-Saxon origin for the stone church at Little Bytham. Up until 1284, Little Bytham was one of several prebendaries of Castle Bytham, a church with pre-Conquest collegiate status.

Based on the damage evidence of the deep, central, roundel on the tympanum and the chamfered back edge of it, this roundel may have once been glazed. This would explain the four narrow slits in the front plane as the spaces which once held the metal armature for a round window.
