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. © Martin Briscoe.
