The world-famous Potala Palace was built in 631 under the supervision of Songtsen Gampo, the 33rd Tibetan king of Tubo. With the disintegration of the Tubo Kingdom, it was severely damaged by natural disasters and man-made disasters. In 1645, the Fifth Dalai Lama rebuilt the Potala Palace to consolidate the local regime of Ganden Phodrang, which was a combination of politics and religion. It was then continuously expanded to its current size. The Potala Palace was designed and built according to the layout of the Buddhist mandala, covering a total area of more than 360,000 square meters and a total construction area of more than 130,000 square meters. The main building is 117 meters high and has 13 floors. It is a large palace-style building complex with a total of 1,267 rooms, including palaces, pagoda halls, Buddha halls, administrative offices, monk schools, monk quarters, etc. Due to its large scale and the high altitude of Lhasa, maintenance is basically carried out by manpower. While we admire the magnificence of the Potala Palace, we should also praise the guardians and maintainers of the Potala Palace.
