The Phra Maha Monthien (พระมหามณเฑียร) group of buildings are located roughly at the centre of the Middle Court, therefore at the very heart of the Grand Palace itself. The traditional Thai style building group is enclosed by a low wall, as this was once the residential and sleeping abode of kings.[26] Thus it is considered the most important set of throne halls in the entire Grand Palace. All of the buildings within the Maha Monthien face north and are arranged from front to back with the public reception hall being at the front, ceremonial halls in the middle and residential halls at the back, all of them inter-connected to each other.
