It has a history of over 13 centuries. With more than 3,000 hours of sunshine annually, Lhasa is famed as " the City of Sunshine". It is the capital of Tibet Autonomous Region and the center of Tibet's political, economic, cultural and religious activities. There are many historic sites and famous relics in the city proper and its suburbs, among which the Potala Palace, Jokhang Temple, Drepung Monastery, Sera Monastery and Gandan Monastery are world famous.
Before the mid-seventh century when Lhasa, later a central town of Tibetan region, was yet to come into being, the area called Wotang was a marshy land of wildness, frequented by antelopes. On one bright summer day, Songtsan Gampo, leader of the Tubo tribe that had risen to power in the Yarlung River Valley, was struck by the perilous position of an area flanked by two steep mountains, while bathing in the Lhasa River, and decided that this was to be the home of his kingdom. This ambitious Tibetan king moved the center of his rule to Wotang and ordered the construction of his residence on the hilltop of Potala. In 641 A.D., Songtsan Gampo who by this time had conquered the whole Tibetan region wedded Princess Wencheng of the Imperial Tang Court. When the princess arrived, she became convinced that Lake Wotang was a devil's heart to be overpowered by the construction of a grand temple after filling up the lake with earth. The princess further suggested that the earth be carried by white goats. This imposing grand temple became a symbol of the kingdom. The temple, later known as Jokhang, was initially named Lhasa, "the Sacred Land" in Tibetan. Over the centuries, Lhasa became a political and religious center of Tibet. Administrative orders were issued from the myriad of imposing palaces; the great temples and monasteries were home to omnipotent liturgical establishment and witnessed the rise of many religious leaders and endless religious ceremonies. The faithful composed the population of the town and Lhasa became a true "Mecca" of Tibet.
