The Potala Palace, located in Lhasa, Tibet, was the chief residence of the Dalai Lama until the 14th Dalai Lama fled to Dharamsala after a failed uprising in 1959. It is now a popular tourist attraction and an UNESCO World Heritage Site.

Built on the side of Potala Hill, Potala Palace, with its vast inward-sloping walls broken only in the upper parts by straight rows of many windows, and its flat roofs at various levels is not unlike a fortress in appearance. At the south base of the rock is a large space enclosed by walls and gates, with great porticues on the inner side. A series of tolerably easy staircases, broken by intervals of gentle ascent, leads to the summit of the rock. The whole width of this is occupied by the palace.

The central part of this group of buildings rises in a vast quadrangular mass above its satellites to a great height, terminating in gilt canopies similar to those on the Jokhang. Tins central meniber of Potala is called the red palace from its crimson color, which distinguishes it from the rest. It contains the principal halls and chapels and shrines of past Dalai Lamas. There is in these much rich decorative painting, with jewelled work, carving and other ornament.
