Bridgend.
Bryncethin, Nazareth Baptist Chapel (1908). The former Hallelujah Wesleyan Methodist Chapel (1908), now in commercial use. The former Peniel Independent Chapel. Only the inscribed stone gives the game away. Although I can make out "built" and "re-built" in the original photo, I can't read the dates. However, the RCAHMW entry says "built in 1820 and rebuilt 1888". It also says it was converted "by 1998". Howard Richter advises that the 1877 O.S. map doesn't show a building on the current site, though there is a smaller, un-named building a few yards away. By the 1899 map, this has been demolished, so it's a reasonable assumption that this was the 1820 chapel. It would have stood about where the yellow bush is in the photo. SS 9115 8394.

Ogmore Vale, St. David (CiW). Bethlehem Independent Church. Christchurch (Methodist and U.R.C.), originally Bethel Primitive Methodist. The former Ogmore Vale Presbyterian Church, now a youth centre. The former Wesley Church, originally Wesleyan Methodist. Pwll-y-Pant Cemetery Chapel. Kingdom Hall of Jehovah's Witnesses, which was perhaps previously a chapel - can you confirm? An inscribed foundation stone bears the date 1895. My appreciation to Janet Gimber who has advised that this was Philadelphia Baptist Chapel. Before the Witnesses, took over, the building spent some time as a "club", according to an old map. All © Gervase N. E. Charmley.

Pencoed.
Pont Rhyd-y-Cyff, Ainon Baptist Church (1825). SS 869 890. This building is marked as a chapel on maps, but has no visible denomination - can you supply it? My appreciation to Howard Richter for advising that this was built as a school (before 1898, as it appears on a map of that date). By 1940 it shows as a church, and on a 1964 map, is St. Stephen's Church (CiW). Both © Gervase N. E. Charmley.

Porthcawl.
Price Town, the former Bethany English Calvinistic Methodist Church (1896, re-built 1905). SS 938 921. Howard Richter advises that (judging from old maps) the chapel extension comprised the nearest section with the two arched windows on the right-hand side; the building has been converted into flats. It appears to have still been a church when the 1992 OS map was published, but the closure date is not currently known. Link. A former chapel - Janet Gimber has advised that this was probably Hope Congregational Chapel, which Howard Richter has confirmed, and he also provides the building date of 1898. The building is not marked as church or chapel on the 1992 map, so was probably closed by then. SS 938 920. Both © Gervase N. E. Charmley. Link1. Link2 (another photo, on an external site). Howard Richter also advises that there was a Free Gospel Mission showing on the 1961-2 OS map at SS 9372 9193, since demolished. The site remains vacant. Can you offer a photo or advise of one currently on-line? Link.
