Tan-y-Cae Methodist Sunday School was built in 1877 in the Simple Round-Headed style of the gable entry type.

A Sunday school had been started about 1846 in an area that had been the site of Calvinist open-air meetings at the end of the 18th century but which by then was one of the poorer districts of the town. Initially meetings were in the open but graduated indoors, using a variety of buildings in the area. Now a purpose-built building was provided, the Sunday school being held in the upper part, whilst downstairs was used for ‘an occasional lecture room and for the purposes of divine worship’. The chapel is now the Elim Pentecostal Church.
