A chapel in Bagby was recorded in the Domesday Book, and again in the 14th century.
It was entirely rebuilt in 1862, to a design by Edward Buckton Lamb.
It has a cruciform plan, but the crossing is wider than the nave, and the transepts are short.
The crossing has a pyramidal roof, topped by a small tower with a spirelet.
Inside, the wooden roof structure is of interest, being particularly complex around the crossing, leaving space only for small quatrefoil lights in each corner.
