Great Gonerby is a village in the South Kesteven district of the county, on the north, western edge of Grantham. The church is on the E side of the High Street, and is built of coursed ironstone rubble and limestone ashlar. It consists of a W tower with a spire, an aisled nave with a clerestorey and a S porch, and a rectangular chancel. The nave, side aisles, and chancel date from the early 14thc. while the W tower and clerestory are from the 15thc. The nave has four bays: the S arcade is entirely from the 13thc, but the N arcade is from the 14th/15thc., except for bay 1 at the E end, which dates from the end of the 12thc. and is recorded here. The church was restored in 1874.
