The building is designed by the French-Swiss architect Charles Beguelin in 1906 in a neo-classical style that popular with King Rama VI and King Rama VII. It was renovated by the King Prajadhipok Institute to serve as a museum exhibiting a rare collection of King Rama VII's personal belongings, including photographs, documents and his biography. King Rama VII ruled in a turbulent time of Thailand's history; he was the last King who enjoyed absolute monarchy, as well as the first King under a constitutional monarchy. Significant events and stories relating to King Rama VII are exhibited, including his succession to the throne, royal activities, political reform, promulgation of the constitution, royal utensils and memorabilia, as well as his life after abdication and death in the United Kingdom. The demolished Sala Chaloem Krung Theatre that used to stand in the nearby area is imitated with old films being projected.
