Pavilion of Regalia, Royal Decorations and Coins  The Pavilion of Regalia, Royal Decorations and Coins is a museum showcasing regalia, royal Thai decorations of the early period, historical Thai money and ornaments used in the royal courts. It is under the supervision of the Bureau of Grand National Treasure, the Treasury Department which has the responsibility to safeguard, conserve, and display national treasures. The museum is inside the Royal Grand Palace, at the entrance to the Emerald Buddha Temple. In 1976, the museum was originally called "The Coins Pavilion" and was established by the Treasury Department to display the evolution of Thai coins. The museum was inaugurated on 14 April 1976, presided over by the king and queen, Princess Maha Chakri Sirindhorn and Princess Chulabhorn. In 1978, the Treasury Department expanded the scope of the collection to include royal regalia and decorations and was renamed "The Royal Regalia, Decorations and Coins Pavilion". The expanded collection was opened on 11 August 1978 and once again presided over by the king and queen, Princess Maha Chakri Sirindhorn, and Princess Chulabhorn. In 1992, after almost two decades and over half a million visitors a year, the need to renovate the museum was apparent. A new interior, a new design, refurbished rooms, and more selective displays were required along with a need to focus on preservation as well as the security of the museum. Once renovations were completed a new name was chosen, "The Pavilion of Regalia, Royal Decorations and Coins". In 2002, the restructuring of the Treasury Department created a new office, "The Bureau of Grand National Treasure". Its primary purpose is to conserve as well as display the items housed by the museum. Since the establishment of this new government department on 3 October 2002, museum has been managed by the Bureau of Grand National Treasure. This room displays the origin, history and establishment of the Pavilion of Regalia, Royal Decorations & Coins, and shows the items used when Their Majesties the King and Queen, Her Royal Highness Princess Maha Chakri Sirindhorn and Princess Chulabhorn presided over the inauguration of “The Royal Regalia and Decorations Pavilion” in 1976 and 1978. Regalia symbolize prestige and rank and were also rewards for good service. It was an ancient tradition where the King bestowed regalia on members of the royal family, courtiers and officials according to their rank and status. The room exhibits the various types of regalia, such as regalia for prosperity, headgear, attire, royal paraphernalia and weapons of rank.
