The former Bethesda Congregational Chapel on River Street. Jo Lewis has  advised that after the chapel closed, it was for a time used as local council offices, but is now a shop. Jo also says that old photos of the chapel show it with two spires, as this photo from the Royal Cornish Museum shows. How much of the chapel itself, which stretched quite a way back from the street, survives, is unclear, but at least some does, as this photo from the rear shows. SW 8244 4487. Both © Paul E. Barnett (2022 & 2024).
