The building is one of the least altered and most elegant public buildings of the center court.
Although the building has been used as a residence and audience hall, its primary purpose which survives to this day is as the lying-in-state place for kings, queens and favored members of the royal family.
The throne hall was built on a symmetrical cruciform plan, the roof is topped with a tall gilded spire.
The hall is considered an ideal archetype of Thai traditional architecture. Every aspect of the exterior decoration of the throne hall is imbuded with symbolism. The hall is built in the shape of a tall mountain to represent Mount Meru, the mythological centre of the universe.
