[2] It is described by the Churches Conservation Trust as a "picturesque early Georgian chapel" with "a lovely unspoiled interior".

[2] The church was built on the site of a former chantry chapel, dedicated to St Helen, founded in about 1525.

[3] Additions were made in 1824, consisting of a west porch, a south gallery, and an upper stage to the tower.

St Mary's is constructed in handmade brick that was originally plastered, with stone slate roofs and with ashlar upper parts to the tower.

[3] Along the north and south walls are large round-headed windows with glazing bars that are continued upwards into intersecting tracery.

Running down the east end is a rain drain pipe, its head being decorated with the arms of Banastre of Bank, and the date 1719.

[3] The porch incorporates a vestry and stairs leading to the panelled gallery which is supported by square fluted columns and occupies the west and south sides.

The church has an octagonal panelled pulpit,[1] an 18th-century font in the form of a simple baluster, a 19th-century cast iron stove decorated with wreaths standing on claw feet[4] and a flagged floor.
