Aberbeeg, St. Illytd, as seen by Streetview in 2021. SO 2180 0196. Link1. Link2. Grade II* listed. The Methodist Church, built as Primitive Methodist. SO 2105 0224. © Gerard Charmley (2011). Its Coflein entry dates it to 1889, re-built in 1905. It doesn't seem to have an internet presence, so may have closed. Aberbeeg straddles the county boundary, so for Christchurch, see Caerphilly.

Llanhilleth, the Parish Church, St. Mark. The town Wikipedia entry dates it to 1898. SO 2171 0080. Coflein entry. The former Wesleyan Methodist Chapel on High Street, at SO 2185 0077. Coflein entry dates it to 1905. The former Anglican Mission Church on Commercial Road. All © Gerard Charmley (2011). The 1:25,000 O.S. map of 1950 shows a place of worship a little way north of St. Mark. Not shown on earlier larger scale maps, it's difficult to say precisely where it stood, but happily Coflein lists it as Hafod-Arthen Road Chapel, demolished circa 1980. I haven't been able to discover its denomination. Its site remained undeveloped in 2021, when Streetview made its most recent visit. SO 2171 0085.

Nantyglo, St. Anne (CiW). SO 1931 1027. © Gerard Charmley (2011). Another view, © Peter Morgan (2011). Recent Streetviews show that it's now called Holy Trinity and St. Anne. Link. Wesleyan Chapel on Wesley Buildings. It pre-dates a map of 1904. SO 1918 1079. © Gerard Charmley (2011). Link. The former Ebenezer Primitive Methodist Chapel (1883) on Queen Street, Garn Fach.
