Potala Palace is the highest ancient palace in the world, reaching 3,767m (12,360ft) at the topmost point. “Potala” named after a holy hill in South India is a Sanskrit word. According to legend: In the 7th century, to greet his bride Princess Wen Cheng of the Tang Dynasty (618 BC-907 BC) of China, the then Tibet King Songtsen Gampo built a 9-storey palace with a thousand rooms up on the Red Hill and named it Potala. Later, with the collapse of the Songtsen Gampo Dynasty, the ancient palace was almost destroyed in wars. What we see at present is the architecture of the Qing Dynasty (1644BC-1911BC) and the continuous expanding work since the 17th century.
