The ordination hall was constructed in the reign of King Rama III at the command of Prince Phithak Thewet. Its area comprises 24 x 43.5 meters. This large, tall brick-and-mortar building employs traditional Thai architectural style. The eaves of the double-tiered roof are supported by square columns. Roof decorations include Cho Fa (apex), Bai Raka (serrated ridges on the sloping edges of a gable) and Hang Hong (finials). The pediment is a carved wood panel adorned with stained glass in the Phuttan (cotton rose) design. The doors and windows are framed with decorative arches with a double-tiered pediment. Surrounding the ordination hall is a low wall with a stupa located at each corner.
