The Phra Thinang Dusit Maha Prasat (พระที่นั่งดุสิตมหาปราสาท) dominates the Maha Prasat group. The throne hall was built on a symmetrical cruciform plan, the roof is topped with a tall golden 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 build in the shape of a tall mountain to represent Mount Meru, the mythological centre of the universe.
