Thirteen stories of buildings – containing over 1,000 rooms, 10,000 shrines and about 200,000 statues – soar 117 metres (384 ft) on top of Marpo Ri, the "Red Hill", rising more than 300 m (about 1,000 ft) in total above the valley floor. The 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 porticos 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. This central member 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 jeweled work, carving and other ornaments.
The most magnificent stupa belongs to the fifth Dalai Lama. It is 14.85 meters tall and inlaid with pearl and jade. The palace also collected a large number of sculptures, murals, scripture and other valuable cultural relics.
