Moriah Sunday School was built in 1870 in the Vernacular style of the long-wall entry type. There is an integral chapel house to the left. The front is of squared stone with rubble to the right gable and a circular vent. It has a central door witha date plaque above, flanked by rectangular windows. In 2002 the chapel was boarded-up and derelict but the chapel house was occupied with a ground-floor porch added.
