Bethesda Chapel. SJ 078 434.

Chapel. The plaque reads "Cernyw Addoldy Y Bedyddwyr".

Chapel at SJ 080 434. Rob Brettle has suggested that this may be the former Salvation Army meeting place at Heol Llundain. He understands that other groups also used this building after the Army vacated it. Janet Gimber's investigations suggest that this was London Road English Congregational Church (Heol Llundain being London Road). It opened in 1879 - some history here, on page 6. It doesn't mention the Army however.

Chapel at SJ 081 434. The inscription over the door indicates it was originally Wesleyan, and built in 1879.
