Selby Town Hall on Brook Street and Gowthorp is a former Primitive Methodist Chapel, seen by Streetview in 2021. It's dated here to 1862, closing in 1956, and it also says that it was preceded by an earlier chapel of 1840 "in a yard off Gowthorpe". SE 6116 3226.

The 1" O.S. map of 1954 shows a place of worship on Millgate, at SE 6134 3267. It was seen by Streetview in 2015. It has a date-stone which says "St. Michael's Chapel 1699, Rebuilt 1903". There is a reference on-line to it having been at one point Unitarian.

Genuki has an entry (including a photo) for St. Richard's Chapel. It had an enormous tripod straddling the church, topped with a cross. It stood on Barwic Parade at SE 6225 3146. It was also seen by Streetview in 2008, at which time it was looking somewhat careworn. Certainly by 2010 it was derelict, so described in a local newspaper item, which also mention the intention of demolishing it, and using the site for housing and a Mission Hall. This was evidently built, and seen by Streetview in 2015.

The Salvation Army Church on Parkin Avenue was seen by Streetview in 2016. Genuki says it was previously St. Mary (R.C.). SE 6218 3158. Link.

U.R.C. on New Lane was, originally Congregational. Its grade II listing dates it to 1865. A 2017 Streetview shows that by that date it was King's Church (link). SE 6134 3227. © Bill Henderson.

Old maps mark a chapel on James Street at SE 6144 3227. This was a Wesleyan Methodist Chapel, whose 1979 grade II listing dates it to 1882. Despite its listed status, it had evidently been demolished before the first Streetview visit in 2008 when new buildings were in situ.

The 1" O.S. map of 1954 shows a place of worship on Denison Road, East Common, at SE 6220 3183. I've not been able to identify it, but it survives, and was seen by Streetview in 2018.
