There was a mediaeval church dedicated to Saint Clement, lying outside the York city walls, which gave its name to the suburb of Clementhorpe.

The nunnery was dissolved in 1536, but the church remained in use until 1585, when its parish was merged into St Mary Bishophill Senior.

It has angled buttresses, and a steep slate roof covering both nave and chancel, topped by a small bellcote.

The nave has side aisles, and the east end is in the form of an apse.

The stained glass in the east window was designed by Jean-Baptiste Capronnier in 1875.
