The pediments are decorated with the figure of Narayana riding on the back of a garuda, this figure symbolizes kingship and the king's association with the Hindu deity. According to legend Narayana descended from heaven in human form to help mankind by alleviating them from suffering. Thus the deity represents all the ideal qualities in a king. The throne hall stands on a high base with convex and concave moldings. The bottom layer, according to Thai beliefs resembles a lion's foot, the lion is a symbol of the Buddha's family and alludes to the Buddha's own royal heritage.
The most unusual feature of the throne hall is the small porch, projecting out at the front of the building. Under this porch stands the Busabok Mala Throne, whose spire echoes that of the larger building itself. The high base of the throne is surrounded by praying deities. During the reign of King Rama I, the throne was used when the king appeared before his vassal states; later it was used for certain ceremonies. The two doors to the hall is situated at the sides of the throne.
