Coningsby is a small town in the East Lindsey district of the county, 10 miles NW of Boston and 17 miles SE of Lincoln. The church stands on the High Street, and has a W tower, an aisled nave with a S porch, and a polygonal apse rebuilt in 1870. The tower is 14thc with a 15thc embattled parapet; the nave arcades are 13thc work and none of the fabric appears earlier than this. Romanesque sculpture is found on an inverted capital now used as a step for the 14thc font.

Coningsby consisted of four holddings in 1066, and this remained the case in 1086 although the tenants were different in every case. The most populous was held by Siward in 1066 and by Robert the Bursar in Demesne in 1086. It was assessed at 9 bovates and 18 households were listed. Next came King William's holding, held by Queen Edith in 1066 and home to 11 households. It was assessed at 1 carucate (8 bovates). Robert held 1 bovate from Drogo de la Beuvrière in 1086, land held by Athelstan before the Conquest and hi=ome to just one villager and a smallholder and their families. Finally Ketilbiorn held one bovate previously held by Siric, and this was assessed at one bovate and housed just one villager and his family.

The capital reused as a font step is clearly from a respond capital, and not 'half a circular capital' as described by Pevsner. The fact that there is some carving on the lateral face of the block behind the capital proper (a final roughing out?) may suggest that the respond was never completed.
