The Central Tibet, mainly means the area of Lhasa. At the altitude of 3658 meters, Lhasa is the holy land of Tibetan Buddhism, also famed as ‘the Sunshine City’ for its annual sunshine time. Lhasa is not only the capital city of Tibet Autonomous Prefecture, but also the political, economical, cultural and regional center of Tibet. It is not so much a geographical designation as a recognition of the centrality of Lhasa in Tibetan history, the imposing Potala Palace and the ancient Jokhang Temple, a place of pilgrimage for all Tibetans. The big three Buddhist monasteries of the Gelugpa sect, Drepung, Sera, and Ganden, are easy to be reached at Lhasa and give the travelers unique acknowledgement of traditional Tibetan life.
