Wat Bowornniwet Vihara Rajaworavihara ( Wat Boworn ) is situated near the Wan Chart Bridge and Banglamphoo Market. Prince Mahasakdipolsep, vice-king of the Third Reign, ordered the construction of this temple along with Wat Rangsisuthawas and it was built between 1824 to1832. At first the temple was called Wat Mai, but when king Rama III invited the future King Rama IV, who was then a monk, to be abbot of the temple , the name was changed to Wat Bowornniwet Vihara. In the Six Reign Wat Rangsisuthawas, which was in poor condition, was incorporated into Wat Bowornniwet Vihara. Wat Boworn is the residence of members of the royal family who enter the monkhood. It has been the residence of many the supreme patriarchs of the Buddhist Church in Thailand, and it is the site of Mahamakut Rajavittayalai, Thailand's first Buddhist institution of the high education.

Because the temple was built during the Third Reign, it was many examples of Chinese art, such as phra ubosot, vihara keng, vihara Phra Sassada and the door of phra ubosot where the Chinese deity " Siew Kang " is carved on the walls as a guardian spirit.

The phra ubosot there are murals that are the work of Khrua In Khong. Of special interest are the painting above the windows illustrating Dhamma teachings using European figures and scenes. The murals also employed perspective as in Western style paintings. There are two presiding Buddha images in the phra ubosot , namely Phra Suwannakhet or Luang Pho To, and Phra Buddha Chinasi, which was brought down from Phitsanulok.
