The Chakri Group was built and resided in by King Chulalongkorn, Rama V (1868-1910). Only the reception portion is now used, consisting of two wings for reception purposes, decorated with galleries of portraiture.

In between is the central throne-hall, now used for various purposes and formerly for the reception of foreign envoys, on the occasions of the presentation of the credentials. It is aptly decorated with four canvasses of diplomatic receptions.

One on the right as one enters depicts the reception by Queen Victoria of King Mongkut's ambassador in London, further on Louis XIV's reception of the mission sent by King Narai of Ayutthaya in "Gallerie des Glaces", in the palace of Versailles; a third, on the other side of the room, King Mongkut's reception of French Envoy, and the fourth the reception at Fontainebleau by Emperor Napoleon III of another Siamese Mission.

The crystal decorations of the hall are mostly presents from foreign monarchs to King Chulalongkorn.

By the side of the inner grand staircase, is the dining hall, attached to the building.
