Croxby is a hamlet in the parish of Thoresway in the district of West Lindsey in NE Lincolnshire. It is in the Wolds, 10 miles SW of Grimsby and 8 miles NE of Market Rasen, and consists of little more than the church situated on a minor crossroads in a landscape of rolling farmland. A church reduced to a shadow of its formal self: a two cell vessel of nave and chancel. It is mostly of the 12thc. though fragments remain of a N arcade built around 1300. A S porch was added in the 17^th/18^thc. Romanesque elements consist of a S doorway, S arcade, chancel arch and font.

Four holdings were recorded in the Domesday Survey. The largest was held by Berengar of Tosny from his father Robert de Tosny in 1086 and by Thorgot Lag in 1066, and was assessed at 3 carucates, Another holding of the same size was helld by William Blunt in demesne in 1086 and by Asfrith before the Conquest. Odo held 2 carucates from Ivo Tallboys in 1086 that were held by Siward before the Conquest, and Odo also held 9 bovates from Norman of Arcy in 1086 that were held by Fulric in 1066. No church or priest was recorded in any of these holdings.

The arcade is late Norman and the reset S doorway may be c.1200, according to Pevsner. He dates the chancel arch to the early 12thc on account of the plain, heavy imposts, and the narrowness of the opening also suggests an early date, perhaps late-11thc. The imposts on the S doorway and the abaci of the S arcade are of the same design as those in the S arcade at Irby-Upon-Humber. The angle rolls in the 2nd order of the arch do not align properly with the imposts. The doorway is clearly reset as it now stands in a blocked arch of the original S arcade of the nave, traces of which can be seen in the exterior wall. The font is suspicious as the surface condition of the whole is clean and smooth, neverthelss both Pevsner and the List Descriprtion accept as 12thc work. The fragment of the base on the SW side on the other hand has very worn and rough surface condition. Is this fragment from an earlier font? The treatment of the interlacing arcades as double rolls is also unusual.
