There used to be a Congregational Church on Pochin Road, at NZ 5499 2085. Its site (2024 Streetview) lies beneath the corner of the green fencing.

There used to be a Methodist Chapel on Cheetham Street at NZ 5495 2075. A map of 1929 identifies it as Wesleyan. It had gone out of use by the middle of the last century. Its site, seen here in a 2023 Streetview from Bolckow Road, lies beneath the house just right of centre, plus the land to its left.

St. Hilda of Whitby (2023 Streetview) on Clynes Road and Birchington Avenue. It post-dates a map surveyed in 1950. NZ 5554 1965. Link.

St. Mary (R.C.) used to stand on a site between Cheetham Street and Bolckow Road, at NZ 5478 2066, and was built no earlier than 1890 (source) and no later than 1892 (from maps). A (presumably) catholic school stood adjacent on its west side. Its site (2012 Streetview) lies mostly beneath the roadway (oddly, called St. James Court) and adjacent parking. I think the photo here is of St. Mary, behind what will be the school with the rose window. The spire of St. Matthew can be seen in the distance.

The site of the demolished St. Matthew on Bolckow Road and Cheetham Street, as seen by Streetview in 2023. It's dated here to 1901, demolished 1979. A 1977 photo of it can be seen here. NZ 5502 2077. It had a predecessor of the same name just a few yards away, shown on a map of 1892 at NZ 5499 2076. 2023 Streetview of the site; the site of the later St. Matthew is a little further to the right. Ken Roddam advises of a building destroyed in a fire in 2025. It stands on Cheetham Street and seems to have been the church hall, or otherwise had some association with St. Matthew's. It was already derelict before the fire as a Streetview from 2021 shows. Coincidentally, Streetview passed by not long after the fire showing the burned out shell. Demolition seems likely.

A map of 1915 shows S.A. Hall on Bessemer Street at NZ 5474 2098. It was still there in 1927. Hall and street have both gone. The site of the hall lies just beyond the industrial unit seen at the centre of a Streetview from 2023.

This source mentions a Primitive Methodist Chapel, but I haven't been able to discover where it was. Another source dates it to 1888, but it's curious that I can't find it on O.S. maps. Could it have later become the Wesleyan Chapel (above)?
