Gyantse is notable for its magnificent tiered Kumbum (literally, '100,000 images') of the Palcho Monastery, the largest chörten in Tibet. The Kumbum was commissioned by a Gyantse prince in 1427 and was an important centre of the Sakya school of Tibetan Buddhism. This religious structure contains 77 chapels in its six floors, and is illustrated with over 10,000 murals, many showing a strong Nepali influence which have survived pretty well intact. They are the last of this type in Tibet.
