The large viharn was built in 1928. Round columns with bell shaped bases and lotus finials support the high red ceiling inside. The standing Buddha image inside is known as the Phra Chao Attarot. Made of a combination of brass alloy and mortar, the image dates back to King Saen Muang Ma (r.1385-1401). Buddhist posters are placed along the walls between the windows, and cabinets with Buddha images and Bencharong ceramics line the walls.
