Church of St Mary (Ruin) North of Birch Hall

The Church of St Mary, a ruin located north of Birch Hall, dates back to the 12th century, with alterations from the 14th and 16th centuries. It is constructed of rubble, partially covered with limestone and brick dressings. The 12th-century nave features two windows in the north wall, one of which is now blocked and has Roman brick in the west jamb. The western window has moulded jambs and a brick head from the 14th and 15th centuries. The north doorway displays a 14th-century segmental arch, and there is a 15th-century rood loft staircase light. The east quoins are made of Roman brick.

The south wall retains the remains of a 12th-century south doorway and one window, along with a 12th-century window that matches the north wall but remains unblocked. An early 16th-century doorway to a stair turret features chamfered jambs and a four-centred head. The 14th-century church has remnants of the original east window.

In the north wall, there are two mid-14th-century windows with two-centred heads and moulded labels, along with remains of two similar windows in the south wall. Between these is a 14th-century doorway with moulded jambs, a two-centred arch, and a label. The west tower comprises four stages, with the two lower stages from the 14th century and the upper two stages constructed of red brick in the 16th century. The 14th-century brick tower arch is two-centred with two chamfered arches. The west windows from the 14th century feature two cinquefoiled lights with a quatrefoil in a two-centred head, complete with a moulded label and covered stops. The west wall also has a 14th-century window, while the early 16th-century windows in the bell chamber are made of brick and have two four-centred lights in a square head.
