This area consists of three main buildings, namely the Audience Hall of Amarindra Winitchai,the Paisal Taksin Hall, and the Chakraphat Phiman Hall.
The Audience Hall was built in 1785 during the reign of King Rama I. It is used for a number of state ceremonies such as that commemorating the birthday 
anniversary of the King. The hall's main feature is a throne which is surmounted by a nine-tiered white canopy, flanked by two seven-tiered white umbrellas 
and backed by a boat-shaped altar. The Paisal Taksin Hall is where the coronation ceremony takes place. It contains the octagonal seat on which the king is seated when receiving the invitation of the representative of the people to rule the kingdom, and also the Coronation Chair on which the king receives the accoutrements of office. In the centre,between the two seats, is a high altar containing the nation's tutelary deity figure, Phra Syam Thewathirat, or Phra Syam for short. The Chakraphat Phiman building was the residence of Kings Rama I, Rama II, Rama III. It has subsequently become customary for the sovereign to spend at least one night here after the coronation to signify the taking up of official residence. On either side of the door leading into the residence chamber are depictions of various seals of state including, among athers,the Lion of the Ministry of Interior, and the Elephantine Lion of the Ministry of Defense, and the Crystal Lotus of the Ministry of Foreign Affairs. The living apartments of the building are entered by mounting as series of steps into a hallway.To the left of the hallway (the east side) is the royal bedchamber. To the rihgt (the west side) is a reception chamber which now houses the royal regalia and accoutrements of kingship.
