St Mary's is constructed in limestoneashlar,[3] and is in Gothic Revival style.[2] Its plan consists of a three-baynave, north and south transepts, a chancel and a west tower containing a porch. The tower is in three stages on a mouldedplinth, with string courses, a frieze, and cornices, one of which is carved with Romanesque-style decoration. The parapet is embattled and there are pinnacles at the corners. In the lowest stage is a doorway with a Tudor arch, above which is a two-light window with a pointed arch and Y-tracery. There are similar windows on the north and south sides of the tower, each with a recessed round window below it. The middle stage has a roundel on each side, the one on the west containing a clock face. In the top stage are double lancet bell openings. On each side of the nave are three three-light windows with pointed arches, and at the west end there is on each side a niche above a roundel. The transepts have parapets, and a blank four-light lancet window in each gable. The side walls of the chancel are blank, and at the east end is a four-light lancet window with transoms, on each side of which is a niche. Over the east window is a coronet carved in high relief, and a datestone inscribed with "1783".[1] Around the exterior of the church are carved heraldic shields containing arms of the families married to the Sherards.[3]
The porch in the tower has an octagonal vault containing a central carved boss. The nave has a plastercoved ceiling, with an arcaded cornice, fluted brackets, and is decorated with a lozenge pattern. At the west end is a wooden gallery with a panelleddado. In the west wall of the gallery is a Coade stone fireplace, above which are the Royal arms on a roundel. The ceiling again is decorated with lozenges, and it contains a central oval dome decorated with putti.[1] On the north and south walls of the transepts are roundels containing depictions of doves. At the east end of the chancel is a dado and a frieze, and a central marblereredos, inlaid with the motif of an anchor, and surmounted by a pediment and an urn. On each side of the east window are double lancet Commandment boards. The stalls are arranged along the north and south sides of the nave. The pulpit is octagonal and panelled, and the font consists of a marble bowl on an oak stem.[1]
The first Earl and his wife and child. By Rysbrack
Most of the memorials were moved from the earlier church.[2] The oldest, dated 1490, is a brass to Geoffrey Sherard and his wife. There is a black and white marble tomb chest dated 1640. The chest bears two life-size reclining effigies and is carved with images of eleven children. There are a number of busts of members of the Sherard family.[1] The finest memorial is that of the 1st Earl by John Michael Rysbrack.[2] It is dated 1732 and consists of a seated woman with a child, and a half-reclining man, all in Roman clothing. There is also a memorial tablet and a hatchment to the 6th Earl, dated 1859.[1] There is a memorial to the businessman, Conservative politician and Olympic gold medalist John Gretton, 1st Baron Gretton, in the church too.
