Cabourne is a hamlet in the West Lindsey district of the county, 10 miles SW of Grimsby. The church is in the centre of the little settlement and consists of a W tower of the 11thc., a nave and a chancel. The entire church was restored in 1872 by A. W. Blomfield. The only feature described here is the font.

The font was discovered under the floor during the 1872 restoration.

The lower cable moulding is a separate piece from the bowl and looks like a later insertion. The original bottom portion of the bowl is missing as is evident from the break line along the base of the bowl now. The semicircular forms on the font body have been read as intersecting arches, and hence the attribution to the romanesque period, but they may be the remaining portions of interlocking rings, a motif commonly found on Anglo-Saxon fonts. The unusual shape of the pedestal raises the question of whether it is an older font being reused as a base, as the older font at nearby Barnoldby-le-Beck had been reused.
