One year after the completion of the
Amphorn Sathan Residential Hall in 1906, King
Chulalongkorn (Rama V) commissioned the construction of a grand European-style reception hall for use by the royal court inside
Dusit Palace. The king named the hall
Phra Thinang Ananta Samakhom. The name was the same as a throne hall built by his father King
Mongkut (Rama IV) in 1859, in the
Grand Palace. The old throne hall was later demolished by order of Chulalongkorn and the name was later reused for the new edifice. Chulalongkorn laid the foundation stone of the throne hall on the 40th anniversary of his first coronation 11 November 1908. Design of the throne hall, to be built in
Italian Renaissance and
neoclassical style, was first given to the Prussian C. Sandreczki. Later, two Italian architects
Mario Tamagno and
Annibale Rigotti took over much of the work, with engineering work by
Carlo Allegri and G.E. Gollo. Marble from
Carrara, Italy and other foreign materials were used. Italian sculptor Vittorio Novi, who would later also work on the Mahadthai Udthit Bridge (สะพานมหาดไทยอุทิศ), was employed with his nephew
Rudolfo Nolli. Construction took eight years and was completed in 1915 during the reign of King
Vajiravudh (Rama VI). The throne hall was used for royal ceremonies and receptions, as well as a gallery for the king's art collection mostly purchased on his two trips to Europe. During the four days of the
1932 Revolution (24–27 June), the
Khana Ratsadon (or the People's Party) used the throne hall as its headquarters. The party also held several princes and royal ministers as hostages inside the hall as it carried out its coup. The events transformed the country's political system from an absolute monarchy to a constitutional democracy. After the revolution, the hall was taken over by the constitutional government and the country's first parliament, the
National People's Assembly of Siam was first convened here on 28 June 1932. Henceforth the hall was used as the seat of the legislative branch until 1974 when the new
Parliament House was opened to the north. After the move, the structure was returned to the royal court and once more became a part of the Dusit Palace. Today many ceremonies are held in the throne hall, the most visible being the state opening of parliament, where the king gives a speech from the throne, opening the legislative session of the National Assembly of Thailand. ==Exterior==
