Grand Palace Layout and Orientation
The palace complex, like the rest of Ratanakosin Island, is laid very similar to the palaces of Ayutthaya, the glorious former capital of Siam which was raided by the Burmese. The Outer Court, near the entrance, used to house government departments in which the King was directly involved, such as civil administration, the army and the treasury. The Temple of the Emerald Buddha is located in one corner of this outer court. The Central Court is where the residence of the King and halls used for conducting state business were located. Only two of the throne halls are open to the public, but you'll be able to marvel at the exquisite detail on the facades of these impressive structures.
The Inner Court is where the King's royal consorts and daughters lived. The Inner Court was like a small city entirely populated by women and boys under the age of puberty. Even though no royalty currently reside in the inner court, it is still completely closed off to the public. Despite the proximity of the Grand Palace and Wat Phra Kaew, there's a distinct contrast in style between the very Thai Temple of the Emerald Buddha and the more European inspired design of the Grand Palace (the roof being the main exception). Other highlights are Boromabiman Hall and Amarinda Hall, the original residence of King Rama I and the Hall of Justice.
