One of Thailand's most highly revered Buddha images was once enshrined in this temple. The image named the Phra Singh or Phra Sihing Buddha image in the Bhumisparsha pose is believed to originate from Sri Lanka.
The temple contains several copies of the Phra Singh image, including an ebony and gold one and a purple jade image. The original is now in the Wat Phra Singh temple in Chiang Mai.
