Parish Church of Saint Mary and Saint George

The Parish Church of Saint Mary and Saint George is a Grade II* listed building located in Church Gresley. This church incorporates part of the nave from a small Augustinian Priory founded between 1100 and 1154 by William de Greley. The church was in a ruinous state when it was restored in 1786, and again in 1872 when the present chancel was built. It is constructed of coursed stone with a slate roof. Much of the internal stonework from the monastic nave may still be present, and part of the 14th-century north arcade remains. A blocked door at the west end of the south wall likely led to the cloisters.

The 15th-century tower is located at the east end of the north aisle and was formerly open to the choir through a lofty arch. The tower is crenellated and buttressed. The nave features two Gothic windows, with a third above the center door on the north side. Monuments from the 17th, 18th, and 19th centuries include an alabaster monument at the east end of the north aisle dedicated to Sir Thomas Gresley, who died in 1699, designed by Sir William Wilson. The monument depicts Sir Thomas in a wig and gown, flanked by two children as weepers, and is surrounded by the arms of his ancestors.

In the south aisle, there is a wall monument to John Alleyne, who died in 1712; the Alleyne family owned the Priory site after 1556. The church also contains three Royal coats of arms, two from the reign of George III. Misericord seats in the chancel and at the rear of the nave are thought to have been carved by Artus Quellin, a Flemish craftsman in the mid-17th century. These seats came from Drakelaw Hall, the home of the Gresley family, although some sources suggest they may have originally belonged to the church.
