High river basin capital called City of the Gods
Lhasa is the capital and largest city of China’s Tibet Autonomous Region, a prefecture-level unit of roughly 29,000-plus square kilometres whose urban core in Chengguan District holds about 300,000 people. The name is often glossed “God’s Home” or “City of the Gods,” and the basin of the Lhasa River still draws Tibetan pilgrims to the Potala, Jokhang, and Ramoche.
Prefecture boundaries track the Lhasa River, chief middle-Yarlung Tsangpo tributary draining some 32,471 square kilometres, across crust that was the last terrane welded to Eurasia before India’s collision raised the Himalayas about fifty million years ago. The terrane is framed by the Yarlung-Tsangpo suture to the south and the Bangong-Nujiang suture to the north; Jurassic–Cretaceous docking with the Qiangtang block may have shortened it by at least 180 kilometres. Average basin elevation near 4,500 metres, active faults, and common earthquakes define the setting; summer monsoon rains from July to September supply most flow, with floods and about seventeen percent of annual runoff in September alone. Yaks, sheep, and goats graze uplands while valleys farm. The 2000 census counted 474,490 residents, 387,124 of them ethnic Tibetans, with Han Chinese then concentrated in urban wards.
Traditional accounts place a fifth-century founding and long closure to most foreigners until the early 1980s. Qing collapse in 1912 opened a period of Tibetan self-rule under the Thirteenth Dalai Lama; after the 1950s incorporation into the People’s Republic, the Fourteenth Dalai Lama fled to McLeod Ganj, India, in 1959 following uprising. Two major highways and the Qinghai–Tibet railway now reach the city, with a Sichuan–Tibet line projected to open around 2030. The Pangduo Hydro Power Station in Lhünzhub County adds 160 megawatts of capacity, and the Yangbajain geothermal field helps supply electricity to the high basin. North Damxung County even crosses the Nyenchen Tanglha watershed to include part of Namtso lake.
Chengguan remains Tibet’s transport, education, and religious centre and its most developed tourist district. Spanning roughly 277 kilometres east–west and 202 north–south, the prefecture borders Nagqu, Nyingchi, Shannan, and Xigazê. The largest tributary, the Reting Tsangpo, rises near 5,500 metres past Reting Monastery; lower reaches widen to 150–200 metres before joining the main stem. Primary schools and basic clinics are widespread even where advanced care is thinner—an administrative capital whose sacred geography still organises daily movement along the river terrace above the Himalayan front.
