Bodfari, St. Stephen. SJ 0925 7012. © Martin Briscoe. Another view, © Carl Hogan. Despite having been painted since Martin took his photo, Carl says it seemed to be in disrepair, so possibly no longer in use. Added in 2024 - an apparently live church website suggests that it still active. Link. Grade II* listed. The lych-gate is also listed, as grade II. A map of 1880 shows Bethel Chapel (Wesleyan Methodist). The building on the site was seen by Streetview in 2023 - it's not apparent whether anything of the chapel survives. SJ 0975 7025. By the time of a 1900 map Bethel was no longer a place of worship, and is now labelled Wesley Villa. Also shown a short distance to the S.E. is another chapel, unfortunately not identified other than Chap. I suspect that it was the successor to Bethel; its Coflein entry seems to conflate the two chapels. Still marked with a "+" on a map of 1961, it has since been demolished. Had it survived it would have stood to the right of the white house, and a little further back from the road (2023 Streetview). SJ 0980 7024.
Brookhouse, Capel Brookhouse (Calvinistic Methodist) on Ruthin Road. Coflein dates it to 1869. SJ 0719 6592. © Gervase N. E. Charmley (2011). The former Baptist Chapel on Brookhouse Road. Gervase remembers the building being derelict about 10 years ago (ca. 2001). Its Coflein entry calls it Brookhouse Independent Chapel, dating it to 1832. SJ 0707 6573. © Gervase N. E. Charmley (2011).
Bryneglwys, St. Tysilio (CiW). SJ 1449 4737. © Eirian Evans. Link. Coflein. Grade II* listed. Older O.S. maps show two chapels, Seion and Ebenezer. Capel Seion lies a little way south of the church at SJ 1449 4723. It hasn't been visited by Streetview, but a photo of it can be seen here. Its Coflein entry calls it Welsh Calvinistic Methodist, and dates it to 1874, the third chapel on the site. Capel Ebenezer is N.W. of the church, at SJ 1418 4746. Coflein has it as Wesleyan Methodist, dating from 1887-1980's, and replacing a predecessor of 1824. In a Streetview from 2011, I think the chapel (or its site) is the single storey building at the left. It was replaced by a shed by 2021 (Streetview).

Carrog, St. Ffraid or St. Bridget (CiW). This source dates it to 1611, replacing a medieval church which stood near the river, and washed away in a flood. It says it stood near a property called Riverdale, but I haven't been able to locate this. Another view. SJ 1112 4357. © Peter Morgan (2012). Link. Coflein. Grade II listed. Baptist Chapel (1895), less than ¼ of a mile east of the church, at SJ 1131 4361. It's dated in its Coflein entry to a re-build in 1896 of a chapel of 1836. © Peter Morgan (2012). Seion Calvinistic Methodist Chapel stands further to the N.E. at SJ 1143 4374. The date-stone, which is in a poor condition, probably says 1872. This is confirmed by its Coflein entry, where it says that it was a rebuild or alteration in that year, the chapel originally of 1832. © Peter Morgan (2012). As of 2024 neither chapel appears to have a web presence, so may be closed.

Bethel Calvinistic Methodist Chapel (1896). A map of 1888 calls it Sion, and Coflein, which dates it to 1807, re-built 1833 and 1897, says it was originally called Capel Mawr. Another view.

Coflein says that 1889 refers to a refurbishment, the chapel originally being of 1842. © Peter Morgan (2013). The date-stone visible in the photo has since been painted over or removed (2021 Streetview). A map of 1888 shows a Baptist Chapel and an Independent Chapel close to each at the eastern end of the village, the former at SJ 0285 4105, the latter at SJ 0586 4103. Neither is marked as a place of worship on a map of 1901, and I suspect that their placement too far east is a rare mistake on the part of the Ordnance Survey, marking Bethania and Carmel on the wrong road.

Derwen, the redundant St. Mary, now in the care of the Friends of Friendless Churches. Two interiors - 1, 2, the altar, font, and a fine window. SJ 0704 5073. All © Iain Taylor. Link. Coflein. Grade I listed. A churchyard cross and a sundial are also listed, as grade II* and grade II respectively. A (former?) Calvinistic Methodist Chapel (2023 Streetview) is shown on O.S. maps to the N.W. of the village at SJ 0679 5090. Coflein dates it to 1843, re-built in 1855, and enlarged in 1908. It's still marked as a place of worship on a map of 1961.

It stands just a few yards from the site of a chapel marked on a map of 1913 as Independent Chapel, at SJ 0597 7910. It, or its site, is the central part (which looks older) of the short row of terraced housing seen in a Streetview from 2023. Coflein dates it to 1842, re-built 1892. Coflein also lists Old Wesleyan Methodist Chapel on Waterfall Road, dating it to 1822, re-built in 1830 and 1869. Presumably the predecessor of Seion, it survives, and was seen by Streetview in 2023. Better photos can be seen on the Coflein entry photo page. SJ 0556 7930. Its grade II listing calls it Coronation Hall.

The former Primitive Methodist Chapel (dated 1914) stands directly across the road from St. David's, and is now in commercial use. SJ 2735 4117. © Peter Morgan (2012). Coflein says it replaced an earlier chapel called Mount Zion - its Coflein entry is here and dates it to 1858. It stood on School Lane, and now serves as part of the school. 2023 Streetview. SJ 2701 4120. Link (for both P.M. Chapels). Coflein includes the demolished Carmel Baptist Chapel (1877-1988) on Woodlands Road, at SJ 2698 4117. Its site was seen by Streetview in 2023, and an old photo can be seen here (no. 10). It had a predecessor, which Coflein dates to 1844, and says survives as the residential properties 1 and 2 Carmel Terrace. Coflein supplies this grid reference - SJ 2681 4118 - which points to Cwmalis Road. The nearer property in a 2021 Streetview is Carmel Cottage. Coflein also lists Seion Independent Chapel of 1851, later known as Capel y Fron. SJ 2717 4118. It was still shown as active on a map of 1951. It stands on Methodist Hill, and was seen by Streetview in 2023. A former Wesleyan Methodist Chapel also stands on Methodist Hill. According to Coflein it was built in 1860, re-built in 1871, and was later Calvinistic Methodist. 2021 Streetview. SJ 2707 4116.

A churchyard table tomb is also listed, as grade II. Moriah Chapel at the northern end of the village.

Capel Hermon (Presbyterian Church of Wales), is also labelled as Capel Moriah on older O.S. maps. By 2024 it was evidently in secular use. SJ 0332 3715. © Peter Morgan (2012). A 2016 Streetview. Coflein entry, which says it was built in 1880. Capel Hananeel (Congregational, 1826, re-built 1879). Coflein dates it to a re-build in 1879, the earlier chapel of 1825. SJ 0363 3718. © Peter Morgan (2012). Although previously listed as possibly the former Wesleyan Methodist Chapel at SJ 0345 3715, Howard Richter has shown that it is in fact the CiW Sunday School. It has a very brief Coflein entry which dates it to 1875. © Peter Morgan (2012). Howard has also advised of some additional chapels - Capel Seion (Wesleyan) is located at SJ 0353 3709, and is a 1884 re-build of a chapel originally built in 1804. It has been converted to residential use. A 2016 Streetview can be seen here. An 1888 map shows a disused "Methodist Chapel (Calvinistic)" at SJ 0336 3695. This is possibly Capel Salem noted by Coflein here ("possibly" because the grid reference and map on Coflein point to an empty field west of the village). If this identification is correct, then it was built in 1822, and re-built in 1880. Streetview shows a building at this site here, and here, the latter showing a pair of old gate piers. This is all rather tentative, so if you can confirm any of this, please let me know.
Llandyrnog, St. Tyrnog, as seen by Streetview in 2023. SJ 1078 6510. Link. Coflein. Grade II* listed. For the listed sun-dial, lych-gate and war memorial, see here. There is a former Wesleyan Methodist Chapel on Gladstone Terrace and Nant Glyd, seen by Streetview in 2021. Coflein dates it to a re-build in 1874, previous versions dating from 1810 and 1836. It was still in active use (presumably as Methodist) in 1961. There's also a former Baptist Chapel a little way S.W. of the village, at SJ 1042 6477. Unfortunately it's blurred out on Streetview, and I haven't found a photo of it. Coflein, which calls it Felin Isa Baptist Chapel, dates it to 1836, re-built in 1868, and says that "by 1980 the chapel had fallen into disuse".
Llanelidan, St. Elidan. Dating back to Norman times, it has been restored several times. SJ 1099 5054. © Eirian Evans. Link. Coflein.

Cefn y Wern Calvinistic Methodist Chapel, 1½ miles south of the village, a tin chapel. Coflein dates it to 1909. In the most recent Streetview (2021) it appears to be derelict. SJ 1072 4781. © Eirian Evans. Two chapels show in the village itself on O.S. maps - Carmel Baptist, and a Calvinistic Methodist. Capel Carmel is at SJ 1071 5040. It has been seen but poorly by Streetview in 2009, the view somewhat obstructed by vegetation, and I haven't been able to find an on-line photo. Coflein dates it to a 1906 re-build of a chapel of 1846. The Calvinistic Methodist Chapel is at SJ 1051 5038. Coflein calls it Brynbanadl Welsh Calvinistic Methodist Chapel, and dates it to 1804, re-built 1876. A 6" O.S. map of 1885 shows the chapel as the building in this Streetview from 2021 - its appearance matches the Coflein description of it being of the "long-wall entry" type. However, the 6" map of 1900 shows the chapel butting up against the road. If this was real then it has been demolished.
Llanfair Dyffryn Clwyd, St. Cynfarch and St. Mary, as seen by Streetview in 2024. Its grade II* listing has a much better photo. Link. Coflein. For related listed features, see here.

Coflein says it was closed by 2003. Grade II* listed. Capel Salem (Calvinistic Methodist) is a little over ½ a mile to the N.E. of the village. Coflein dates it to 1886. SJ 1421 5586. © Eirian Evans. Just a couple of hundred yards to its south is the former Capel Seion (Baptist) at SJ 1424 5565. It was seen by Streetview in 2009. It's dated by Coflein to 1840, closing by 1983

Llidiart y Parc, the former Beulah Chapel (1905), now a private residence. Curiously, it doesn't appear on an large scale O.S. map revised in 1910 and published in 1914.

Maeshafn (or Maes-y-safn), the former Calvinistic Methodist Chapel. Coflein dates it to 1900, a re-build of an earlier chapel of 1820. The date-stone is for 1820, but makes no mention of the re-building. SJ 2019 6102. © Eirian Evans.

Since Mike took his photo the chapel has evidently been closed - Streetviews show that the church notice-board was removed between 2011 and 2017. 2023 Streetview. The Coflein entry for its predecessor dates this chapel to 1925. The earlier chapel (2011 Streetview), is dated by Coflein in the same entry to 1860, and stood a little way to the west at SJ 0608 8085. O.S. maps mark another chapel near the junction of Ffordd Tanrallt with the main road at SJ 0620 8085. Pre-dating a map of 1878, where it's labelled as Calvinistic Methodist, Coflein calls it Mynydd Seion, and dates it to 1860. The photo attached to the entry is incorrect however, showing instead the 1925 Salem chapel - unless the chapels were identical of course, which seems unlikely. It stood set well back from the A547 - access to it may well have been from Ffordd Tanrallt, its site now being parking (2023 Streetview), presumably for the adjacent housing. It was still marked as active on a map of 1961.

Pen-y-Stryt, Piscah Chapel. Coflein calls it Pisca, and dates it to 1817, re-built in 1841. It shows as still active on a map of 1961, but has evidently been closed and converted since then. SJ 1994 5194. © Eirian Evans.

I also couldn't find a Streetview showing the church. I suspect that rather than being restored it was demolished, and its site commemorated in the street name of Lôn yr Eglwys surrounded by a housing estate (2023 Streetview).
