The church is situated just to the S of the village of Great Langton. It consists of a long, narrow nave and chancel, as well as a bellcote. The exterior walls of the nave and chancel have been rendered with roughcast. The surviving Romanesque elements are the doorways in the S and N walls of the nave.

In 1066, Great Langton, or ‘Langeton’ was jointly owned by three individuals, two of whom were Danish (or, at least, had Danish names). By 1086, the ownership of the land had passed to Alan of Brittany (who began the building of nearby Richmond castle), though the Doomsday Survey reports the area as ‘wasted’. In the latter part of the 12thc, the church at Great Langton was granted to St Agatha’s abbey by a certain Ismania, who was the daughter of Roald the Constable of Richmond castle. This abbey is situated at Easby, on the outskirts of Richmond. It was founded in 1155 by the same Roald.

The covering of the nave and chancel walls with roughcast render makes examination of the masonry almost impossible. However, the narrowness of the nave might suggest that it was constructed in the first half of the 12thc. The form of the capitals in the S doorway would be consistent with a date of c. 1140, assuming that the doorway was inserted at the time of the construction of the nave. The doorway in the N wall of the nave looks later and probably dates from the end of the 12thc.
