Llanon, Capel Siloh (Welsh Independent), dated by Coflein to 1864. SN 5162 6713. © Mike Berrell (2012).

Poorly seen by Streetview (it's the last building at the end of the path on the left), photos are available on the Delweddau tab of its Coflein entry, which dates it to a re-build in 1865 of a many times re-built chapel originally of 1762.

On an O.S. map of 1889, a little way south of the village at SN 4415 4585, is marked Unitarian Chapel (2023 Streetview). It's dated in its Coflein entry to 1878-9, successor to an earlier chapel. Its grade II listing dates its predecessor to 1834, but annoyingly only locates it "at the crossroads". Fortunately the same 1889 map already mentioned shows it at the crossroads in Rhyd-Owen, a little way to the south at SN 4436 4521. See Rhydowen, below.
Ponterwyd, Capel Ponterwyd (Welsh Presbyterian). A map of 1886 labels it as Meth. Chap. (Primitive). This source discusses the possibility that it may originally have been Wesleyan. Coflein dates it to 1800, with re-builds in 1821 and 1854. SN 7488 8091. © Gerard Charmley. Grade II listed. Coflein also has an entry for an un-dated Mission Room a little way south of the village. It was seen by Streetview in 2021, and has evidently been converted to residential use. But for the small belfry, it would have been difficult to have identified it as a former church.
