[1] The stonework in the tower is in poor condition and hence the church is listed on Historic England's Heritage at Risk Register.

[2] The ancient St. Mary's Chapel located in Atherstone dates from the early 12th century, when the monks of Bec made a donation of 12 acres (4.9 ha) to a house of friars and hermits, later referred to as “Austin friars."

According to Nichols, the chapel was granted to Henry Cartwright in 1542, then left abandoned and neglected until 1692, when Samuel Bracebridge settled a yearly sum for the parson of Mancetter to preach there every other Sunday in the winter season.

This drastic alteration probably aroused some controversy, although the fine architectural drawing of the chapel made by Jacob Schnebbelie in 1790 prompted Nichols to assert that “the new tower provides a good effect."

This was replaced in 1898, when an organ by Henry Jones and Sons was obtained from Christ Church, South Banbury.
