Carlton Scroop is is a small village and civil parish in the South Kesteven district of Lincolnshire, 6 miles NE of Grantham and 7 miles W of Sleaford. The church consists of a Romanesque W tower, a 14thc. two-bay nave with N and S aisles, and a 13thc. chancel and S porch. The upper two stages of the tower were rebuilt around 1632 after the steeple came crashing down onto the nave. In 1848 James Fowler restored the church and later in the century the roof line was raised. Romanesque survivals of sculpture here are the tower arch leading into the nave and the blocked N doorway of the nave.

The Domesday Survey cites a church and a priest in Carlton Scroop in 1086 in the possession of William of Warenne, lord of Lewes and Earl of Surrey. It was assessed at 7 carucates and was held before 1066 by Earl Harold. Further land was held by Count Alan of Britanny in 1086, but it was waste.

The imposts on the E side of the tower arch are actually continuous with the plain stringcourse that extends N and S along the nave E wall. Though the arch has certainly been cleaned and has had some restoration work, it appears to be in its original form.

The use of dogtooth in a hollow on the label recalls the same treatment at Lincoln Cathedral on the 3rd order arch of the N doorway on the W façade (see Zarnecki (1988), 26 and fig. 16). Stocker and Everson also note the use of this motif at St. Mary Guildhall in Lincoln and based on these two examples place the dating of the Carlton Scroop tower at c. 1150-1175. The S label stop is produced differently that the N label stop. It is just the face whereas the N stop also includes the neck of the figure, as does the keystone corbel. Additionally, there are stone extensions with broken edges to the L and R of the face on the S label that suggest the label continued in those directions.
