Building was started in A.D. 1807 during the reign of King Rama I and was completed in the time of King Rama III. It stands on a double base, surrounded by walls. The verandah around it was built in the style of early Bangkok, influenced by the style of Wat Mongkhon Bophit in Ayutthaya. The roof is in double tiers. Open porches are both in front and at the back. The square pillars are topped with lotus capitals.
