Bureau of Grand National Treasure
The Bureau of Grand National Treasure  is a Thai government agency within the Treasury Department, Ministry of Finance. Its main responsibilities are the safe-keeping, restoration and conservation of the national treasures such as regalia, royal ceremonial and decorative items as well as ancient Thai money, and publicising them to the general public and tourists. History
The task of safe-keeping and conserving the National treasures was formerly performed by the Royal Treasury Department. Following the transition from an absolute monarchy to a constitutional one in 1932, the government  separated the national treasures from the crown property and assigned the task of their safekeeping  to the Royal Treasury, a government agency under the supervision of the Royal Finance Department, which in 1936 became the Treasury Department. The history of the Bureau goes back to 1976 when Suthon Satheinthai, the Director General, realised the importance of promoting ancient Thai money and   coins to the public and tourists. By Royal permission, a section of the Bureau of the Royal Household’s office was used as a museum, which was named “Thai Coin Pavilion” and was under the supervision of the Central Finance Division. King Bhumibol and Queen Sirikit, together with Princess Sirindhorn and Princess Chulabhon presided over the opening ceremony on April 14, 1976

In 1978, the museum expanded its exhibition by including the display of royal regalia and royal decorations and changed the name to “The Pavilion of Regalia, Royal Decorations and Thai Coins”. The Royal family once again graciously presided over the opening ceremony on August 11, 1978

The Pavilion was elevated to become “The Division of Regalia and Coins”, with the responsibility to oversee the display of regalia, royal decorations and coins at “The Pavilion of Regalia, Royal Decorations and Thai Coins” which was later in 1992 changed to the current name, “The Pavilion of Regalia, Royal Decorations and Coins.”  

In 1997, the Division of Regalia and Coins was included under the newly established, Bureau of Monetary Management. Later in 2002, it was separated and promoted to the Bureau of Grand National Treasure   reporting directly to the Treasury Department; it has been assigned the safe-keeping  and conserving the national treasures as well  disseminating information about  the national treasures to tourists and the general public through displays and exhibitions. The Bureau of Grand National Treasure is divided into five central divisions: the Conservation and Registration Division, the Grand National Treasure Exhibition Division, the Product Management Division, the Revolving Fund Management Division, the Administration Division, and two regional divisions, which are the Treasury Pavilion 1 in Chiang Mai Province and Treasury Pavilion 2 in Songkhla Province.
