This temple is located at the foot of the Rama I Memorial Bridge on the Bangkok side. Built in the late Ayutthaya period by a Chinese merchant, it is otherwise known as Wat Liap and is one of the 3 principal temples of the capital which include Wat Ratchaburana, Wat Ratchapradit and Wat Mahathat. It had been regularly restored since the reign of King Rama I through to the reign of King Rama VII, except in the sixth reign. Some of the temples principal buildings, especially Phra Ubosot the ordination hall which houses mural paintings by Khrua In Khong, were badly damaged by bombing during World War II. The buildings were later restored to their good condition as they appear today.

Prang: Built in the reign of King Rama II and has 28 notches on its five-level lotus base. Each level is surrounded by figures of demons, and the top of the prang is a crown with a noppasoon (Siva's weapon).

Ubosot: During World War II, this area was damaged by bombing. The present ubosot was rebuilt to the design of Prof. Luang Wisan Silpaka (Cheua Patamachinda).

Part of its historical importance is that Khrua In Khong, the monk praised as a master artist at the court, was ordained at this temple. He was "a pioneer of incorporating the European style into traditional Thai art by introducing perspective"
