A procession was held at Bangor on Saturday evening which numbered 2000 persons, and much enthusiasm was shown… After Parading the various streets, a revival meeting was held at the Tabernacle CM Chapel – the largest building in the city – which was packed until 11.00pm… On Sunday evening, 52 converts were added to Sion (W), Hirael, Bangor. Twenty were immersed at Penuel Chapel.

It looks like the building has been converted into an industrial premise.
