The first church building in Bishop Thornton was constructed in about 1460, on the initiative of John Walworth.
The three-stage tower (54°04′25″N 1°36′07″W / 54.07354°N 1.60200°W / 54.07354; -1.60200) survives and is a Grade II listed building.
The small church is in the Decorated Gothic style, and it has an octagonal bellcote.
The chancel has four small windows, which were relocated from the old church.
There is an octagonal font, and an organ built by James Jepson Binns.
