The church is siituated in the main street running south through the village, and is built of Limestone rubble with limestone ashlar facings. It consists of a W tower, nave with S aisle and S porch, and a rectangular chancel. The tower is 11thc. with long and short quoins and no buttresses, The nave has a 14thc tower arch and the arcade was added in the 13thc. The N wall was rebuilt in the 19thc., when the chancel was largely rebuilt too. The only Roamanesque feature is the font.

This was held before the Conquest by Earl Edwin. 4 brothers held 2½ carucates in 1066, held by Joscelin fitzLambert in demesne in 1086, along with half a church. Finally Alwine held 5½ bovates in 1066, and William held it from the Archbishop of York in 1086.

Arcaded fonts are common in Lincolnshire, but this one is unusual in the number of its arches, the inaccuracty of its carving and the use of pointed arches that are not part of an intersecting arcade.
