The eastern wing of the Palace was extended in 1813, during the fiftieth anniversary of the reign of Nasser ed-Din Shah Qajar.     SinceThe Palaces, in the northern section of the Golestan garden, consisting of the Museum hall, the Mirror hall, the Diamond hall, the Ivory hall, and the Glass hall were constructed before the other sections of the Palace. In 1878, Nasser ed-Din Shah, influenced by what he had seen during his first visit to Europe, added a Museum in the form of a large, first-floor hall decorated with mirror work, where some of the priceless Crown Jewels were put on display.         SinceIn 1966, the palace was converted into a Museum and opened to foreign and official guests. The official ceremonies of the Qajar kings (Nasser ed-Din Shah and Fath-ali Shah Qajar) were held in the Golestan Palace.
