The ubosot enshrines two large golden Buddha images. Seated on a pedestal is the Wat Bowonniwet’s principal Buddha image, the Phra Phuttha Chinasi. The Sukhothai style image in the “Calling the Earth to Witness” posture was moulded in 1357. Originally enshrined in theWat Phra Si Rattana Mahathat temple in Phitsanulok, the image was moved to the Wat Bowonniwet in the early 19th century. The image is flanked by two standing images in adoration. Seated in front of the Phra Phuttha Chinasi are three small images of former abbots of the temple. Behind it is another, larger Buddha image named Luang Phor To.
