Probable former church on Chapel Street. I've tried tweaking the photo to bring out the text on the sign, but can't read it. Possibly Methodist? SW 517 403. © James Murray (2009). Janet Gimber has advised that this was a Methodist New Connexion Chapel - showing as such on a map of 1878. By 1908 it was a "Drill Hall". She has also provided this link, which has a photo which shows that it has been renovated since James took his photo, and it is now in commercial use.

Halsetown
Ebenezer Chapel (Bible Christian) as seen by Streetview in 2018. Founded in 1832, this building was later closed for some years, but re-opened again in 1902. More photos can be found here. SW 5054 3892. A history (pdf).
The Old Chapel, now used as a holiday cottage. Built as Wesleyan Methodist in 1832. SW 5075 3870. © Paul E. Barnett (2014). Link.
The former St. Mary's Mission Church was built as Halsetown Wesleyan Teetotal Chapel (1845). St. Mary was a Mission from St. John's in the Fields, opening in 1878. At some uncertain date, it closed, and following restoration in 1977 it has been occupied by a potter. SW 5039 3874. © Paul E. Barnett (2014).
