Constructed between 1875 and 1876, this is the third Welsh Calvinist chapel to have been built in Newtown. Designed by the famous Liverpool architect Richard Owens, and built at a cost of £2300, the chapel was constructed in the gothic style. The front elevation is in squared masonry and sandstone dressings with a central door and two buttresses to the main gable (from which spirelets have been removed). The remainder is in yellow brick beneath a slated roof to a tiled ridge. It probably seated about 450 people but is now in a sad state of disrepair, the holes in the roof have lead to some major rot to one side of the building.
