Sanphet Prasat Palace in Ayutthaya

The structure and style of roof was taken from the old pulpits and such-like furniture in the main (western) hall of Wat Phra Buddha Chinnarat, Phitsanulok Province. The roofs and roof spires are modeled after those of the Aphon Phimoke Palace within the Grand Palace in Bangkok; the roofs over the wing as well as the spire and the spired roof that rises above the central room, its double series of lotus mouldings above seven diminutive stories with their false gables and their naga eaves brackets and fascia boards, are all sheathed with tin plate, as are the roofs over the wings, the short turned posts along the four ridges, the naga barge board over the gables and even the ends of the roof purlins.
The hornlike finial on the roof ridge or chaufa at the extremities of the ridge lines as well as the hall gables naga barge boards are from Wat Pho, Bangkok. The eaves brackets are those of Wat Sala Pun in Ayutthaya Province. The stucco gable panels above the palaces porches are based on the stucco gables from Wat Khao Bandai It, Phetchaburi Province.
The Mother of Pearl inlaid doors and windows follow those of the mondop over the Buddhas Footprint at Phra Buddha Bat in Saraburi Province.
The palace was used in many important state ceremonies. The palace hall was the room where Chavalier de Chaumont presented his credentials on behalf of Louis XIV, and of which de la Loubere, his aide, had given a vivid description. In the early Rattanakosin era, King Rama I had Indra Phisek Palace Hall modeled after the Sanphet Prasat. Unfortunately, the Indra Phisek was burnt down in a huge fire and Dusit Maha Prasat Palace was built on the same site but by a different plan.

The Sanphet Prasat at Muang Boran was once used as a reception hall by His Majesty the King to welcome Queen Elizabeth II and her consort on February 11, 1972. That day is considered the official opening day of Muang Boran.
