Church of St Mary

The Church of St Mary is a parish church dating to 1914, designed by Temple Moore. It is constructed of coursed ironstone rubble with ashlar dressings and has plain tile roofs. The church comprises a west tower, a nave with a central arcade, a rectangular chancel, a north vestry, and a low outhouse.

The west tower features a broad buttress to the north with a pointed west doorway, an ashlar surround, a hoodmould, and a plank door. Above the door is a two-light rectangular window with leaded lights and a hoodmould. A small rectangular light is set low in the southeast corner of the south side. The tower has paired bell openings on all four sides, set under rectangular heads with wooden shutters punctuated by heart-shaped openings. The north aisle has a two-light rectangular window with leaded lights and a hoodmould. Further north, a large buttress is set back, followed by another two-light rectangular window with leaded lights. A low coal bunker and outhouse feature a doorway with a Caernarvon head and plank door. The north vestry includes a chimney, a two-light rectangular window with leaded lights and a hoodmould, and a door with a Caernarvon head and plank door. The gabled east end of the vestry has a three-light rectangular window with a hoodmould. A stone set in the east corner of the chancel commemorates Percival Laurence, rector of Walesby, 1879-1913. The gabled east end of the chancel has a pointed window containing three cusped lights with 19th-century tracery and a hoodmould. The south side of the chancel has a three-light rectangular window with leaded lights and a hoodmould to the east, and a doorway with a Caernarvon head and plank door to the west, beyond which is a pointed window of two cusped lights with 19th-century tracery and a hoodmould. The projecting south nave aisle has a two-light rectangular window with leaded lights to the east, and a large buttress with a set-off, followed by a three-light rectangular window with leaded lights and a hoodmould.

Inside, a striking two-bay nave arcade is defined by very tall piers of complex design and pointed arches with rich mouldings. A pointed moulded chancel arch has an outer order running into a stringcourse with small paired pointed openings that create a ‘screen-effect’. Two plain pointed arches lead into the north vestry. C15 traceried three-light windows are set in front of Moore's windows in the south east chancel window and the east window of the vestry, creating a visually appealing effect. All fittings date to 1914, with the exception of a C12 octagonal stone font on a scored supporting column with an octagonal abacus, and two ornate C19 chairs.
