Zêtang or Zedang or Tsethang
Zêtang, also Zedang or Tsethang, is the fourth largest city in Tibet and is located in the Yarlung Valley, 183 km southeast of Lhasa in Nêdong District of Shannan, Tibet Autonomous Region of China. As capital of Shannan City, it "...exercises direct control over the affairs of 13 counties: Gongkar, Tranang, Nedong, Changye, Tso-me, Lhodrok, Nakartse, Zangri, Chutsum, Lhuntse, Tsona, Gyatsa and Nang."
Zêtang has been the capital of the Yarlung region since antiquity and was the seat of the ancient emperors of Tibet and, as such, a place of great importance. In the 19th century, it is said to have comprised some 1,000 houses, a bazaar, a gompa and a fort.
As the capital of Shannan, it is the second-largest settlement in the historical Ü-Tsang region. It lies at an elevation of 3,100 metres (10,170 ft) above sea level and has a population of approximately 52,000 persons. It is only about 4 km to the northeast of the town of Nêdong and they have now essentially merged into one city.
The 14th century monastery of Tsetang, Ganden Chökhorling, was originally Kagyupa but was taken over by the Gelugpas in the 18th century. It was destroyed during the Cultural Revolution in the 1960s but has been restored since. Ngamchö is also a Gelugpa monastery and contains the bed and throne of the Dalai Lama and has a chapel devoted to medicine. The Samten Ling and Drebuling monasteries of the Sakyas still remained in 1959 but have since been destroyed and mostly built over. There is, however, the reconstructed Gelugpa Sang-ngag Zimche Nunnery, in the ruins of Samten Ling with a 1000-armed statue of Chenresig (Avalokiteshvara) said to have been made by Emperor Songtsän Gampo (605 or 617? - 649 CE).
