Lhasa is the capital city of the Tibet Autonomous Region and has long been the center of politics, economy, culture and religion in Tibet. Lhasa means "holy land" in the Tibetan language.
History
The history of the city dates back to the 7th century A.D., when the Tibetan king Songtsen Gampo conquered many tribes, united Tibet, transferred the capital from Yarlung to Lhasa, and established the Tubo Regime. In the time of the 7th Dalai Lama, a very famous palace, Norbulingkha was built, which is 2 kilometers away from the Potala Palace. From then on, the ancient section of Lhasa city was formed, with Potala Palace as its center, and Barkhor Street and Norbulingkha Palace on each sides.
Location
Being the religious and political heart of the Tibetan world, Lhasa sits on the north bank of the Kyi Chu, surrounded by colossal mountain ranges to the north and south. The altitude of Lhasa is around 3,650 meters.
Area and Population
Lhasa governs seven counties and one city borough. The area of Lhasa is about 30,000 square kilometers while the city zone is 523 square kilometers. The entire population of the city zone is close to 130,000, and consists of Tibetan, the Han nationality and the Hui nationalities.
Attractions
The first hint that you are entering the traditional capital of Tibet is the red and white palaces of the Potala, home to Tibet's spiritual and temporal leaders - the Dalai Lamas since the 17th century. The Dalai Lama, the other enduring symbol of Tibetan purity and mystery, fled the grounds of his summer residence, the Norbulingka, more than 40 years ago.All Tibetan

Climate and Tips
This area is inaccessible for tourists between December and January due to heavy snowfall and poor weather conditions. August is the rainy season here when landslides are common. The hottest month here is June, with high temperatures of 22 degrees C. The sun here can be very strong too, so make sure you take plenty of sun block and a hat to protect from the harsh rays.
With Lhasa being such a high altitude, travelers should beware of "altitude sickness" a condition which affects many people, which is characterized by shortness of breath, dizziness, weakness and, in severe cases, serious brain or lung problems. A slow journey from lower altitudes, by train or road, rather than a quick one by plane, can help prevent this. If experienced, administration of oxygen can help relieve this condition. Neglecting the condition can cause serious health problems and even death. Prior to travel there, prospective travelers should consult a doctor for advice.
