11th November 1908, Foundation Stone Laying Ceremony of Ananta Samakhom Throne Hall.

        Ananta Samakhom Throne Hall is the only marble throne in Thailand. It was built with white marble from Carrara, Italy. It was inspired by the dome of St. Peter's Cathedral, Vatican City and St Paul's Church of London. The interior is decorated with frescoes related to the important activities of the King's reigns.

        The Ananta Samakhom Throne Hall featured a large central dome made of copper with a diameter of about 15 meters and included six sub-domes, but due to rust, it changed its color to a bluish-green color today.
