Capel Engedi (Calvinistic Methodist) on New Street was previously and incorrectly listed as Gwladfa Patagonia. The confusion will have arisen because there is a sign, headed Gwladfa Patagonia (seen by Streetview in 2018), referring to the chapel's involvement in the decision to emigrate to set up a settlement in Patagonia. My thanks to Howard Richter for the correction. It's dated above the columns to 1842, re-built in 1867. SH 4812 6259. © Martin Briscoe. Coflein entry, which advises that the chapel was sold in 2014. Grade II listed.

Possible unidentified Church. © Martin Briscoe. Janet Gimber has advised that though this has been a Masonic Hall since at least 1965, it was originally Wesleyan Methodist.
