Phra Ubosot or Chapel is a place for religious ceremony, such as reciting of Prātimokṣa (Fundamental rules of Buddhist monks) on Buddhist day of observance and ordination ceremony. Bai Sema (Buddhist stone marker in Thai temple) and Kampheng Kaew (low wall) can be found outside, separating the Ubosot during Buddhist ceremony. Inside the chapel, Phra Phutta Thewawirat or Luang Por Khao (the White Buddha) is the principle Buddha image of the building. The Buddha image sits on Vechyanbusabok, an artistic reflects of the throne of Indra. In front of Luang Por Khao, two standing Buddha images in the post of calming the ocean stand in full regalia. On the right, the picture of Princess Wilat drew and donated to the temple by the Fine Art Department, Ministry of Culture. On the other side, a statue of King Rama III, the founder of the temple, can be found.

Outside the Ubosot stand four pagodas in each direction. These pagodas were built in a unique fashion of early Rattanakosin period in the form of “corn shape” pagoda, which is characterized by tall and steep tower that slowly shrink and round up on the top, similar to the shape of a corn. The total height of each pagoda is 15 meters, including the 5 meters octagon foundation. Each pagoda stands in the cardinal direction with Thao Chatulokaban, the Buddhist four heavenly kings, house inside the housing part of the pagoda. The stone pillars in front of each pagoda were carved into stone incense with Chinese dragon adorning the surface. There were four Buddha images installed at the foundation of every pagoda. However, three of them were stolen from the temple over the years.
