On the eastern wall of the Grand Palace there are two buildings. They are Sutthaisawan and Chaichumphon.

Phra Thinang Sutthaisawan Pavilion

          Between Thewaphithak and Sakchaisit Gates on the eastern wall of the Grand Palace a pavilion was built in imitation of Phra Thinang Chakrawat Phaichayont on the wall of the Royal Palace in Ayutthaya . When it was first built during the reign of King Rama I, it was only an open wooden payilion without any roof decorations. It was then called “phra Thinang Phlapphlasung” from which the king watched parades and the training of elephants.

King Ranma III had the original pulled down to replace it with a Prasat in bricks and mortar, as a public from the balcony. On the eastern side there is a wooden gallery added in 1949 with a special window called Sihabanchon from which the king gives audience to the public. Thr roof is in five tiers with a Mondop finial while the roofs of the front and rear porches are in two tiers. The side porches which are longer have roofs in four tiers. There is no niches above the doors and windows. When it is fully opened it is almost like an open pavilion. Originally King Rama III called it “Phra Thinang Sutthasawan” but later King Rama IV changed the name to “Phra Thinang Sutthaisawan”.

Phra Thinang Chaichumphon Pavilion

This small pavilion has a roof of two tiers covered with the usual decorations in black it so that he might observe processions to the Brahmin shrines. It was as a site for the worship of Phra Siam Devadhiraj and other heavenly beings during the reign of King Rama V.
