Langton is a small village in East Lindsey, 1½ miles W of Horncastle. The church is at the E end of the village and is a small building of greenstone, limstone and red brick. The original church on the site was medieval and had a W tower, whise foundations are visible at the W end. It was restored in 1750 and again, by W. Scorer, in 1890, so that now it is mostly his work. It is a small church with nave and chancel only. A coped coffin lid bearing sculptural decoration was reset into the rebuilt W wall of the nave in 1891; previously it had been located in the chancel pavement, and this is the only Romanesque feature.

Langton was sokeland of Horncastle, held by the king in 1086 and by Queen Edith in 1066. The ploughland was rated at 3 carucates (including sokeland at 'Torp' in Woodhall). A second holding was held by one of his men from the Bishop of Bayeux, and that was assessed at 1 carucate and was held by Leofsige in 1066. Finally, Arnketil and Aelfric held 2 carucates there in 1066, which was held by Geoffrey from Drogo de la Beuvriere in 1086. In none of these estates is a church or a priest mentioned.

The Historic Environment record notes that the font has been assembled from various pieces, including the keystone of a Norman vault rib from Kirkstead Abbey.
