Church Of St John

The Church of St John is a Grade II* listed building located in Adwick Upon Dearne. It dates back to the 12th century, with 13th-century and later windows. A vestry was added, and the chancel arch was replaced in 1910 by A. C. Martin of London. The church is constructed from pebble-dashed rubble sandstone and features a Welsh slate roof.

The structure includes a nave with a south porch and a west bellcote, along with a narrower chancel that has a north vestry at the junction with the nave. The gabled porch has a slightly pointed arch with an impost and weathered stone above, along with shaped kneelers and renewed gable copings. Inside the porch, there is a tall 12th-century round-arched doorway that appears to have been altered. To the right of the porch is a Y-tracery, 2-light window with an offset buttress beyond. The former north door has been blocked and replaced with a square-headed, 2-light mullioned window, while a tall, square-headed, 3-light window is located to its west, and a window with 2 cusped, ogee-headed lights is to its east. The bellcote features a battered projection with a rectangular, 2-light west window and a pair of round-arched bell-openings set beneath an ashlar-coped gable, which also has shaped kneelers and gable copings.

The lower chancel has a south door with a 2-light mullioned window to its left and two 13th-century lancets to its right. There are three early 19th-century headstones set beneath the 2-light, Y-tracery east window. A lancet is located to the east of the north vestry, which features a Y-tracery north window and a door on its west side.

Inside, the chancel arch is double-chamfered and dates from 1910, replacing the former Norman arch. There is a square piscina in a chamfered, arched recess and an aumbry recess. The roof features arch-braced trusses, and the royal coat of arms is displayed above the blocked north door. Late 19th-century fittings include a pulpit made from older pews with arms, and the east window was added in 1883.
