The Potala Palace is located in Lhasa, Tibet Autonomous Region, China. Situated on Marpo Ri hill, 130 meters above the Lhasa valley, the Potala Palace rises a further 170 meters and is the greatest monumental structure in all of Tibet. Although a palace was already built here in the 7th century the construction of the present palace began in 1645 during the reign of the fifth Dalai Lama and by 1648 the Potrang Karpo, or White Palace, was completed. The Potrang Marpo, or Red Palace, was added between 1690 and 1694. The Potala Palace remained the residence of the Dalai Lama until the 14th Dalai Lama fled to India, after the Chinese invasion in 1959.
