Ganden Monastery (also Gaden or Gandain) or Ganden Namgyeling is one of the "great three" Gelug university monasteries of Tibet, China. It is in Dagzê County, Lhasa. The other two are Sera Monastery and Drepung Monastery. Ganden Monastery was founded in 1409 by Je Tsongkhapa Lozang-dragpa, founder of the Gelug order. The monastery was destroyed after 1959, but has since been partially rebuilt. Another monastery with the same name and tradition was established in Southern India in 1966 by Tibetan exiles. Ganden is 40 kilometres (25 mi) northeast of Lhasa. The monastery lies in a hilly natural amphitheater. from the kora route around the monastery there are dramatic views over the valleys that surround it. Ganden Monastery is at the top of Wangbur Mountain, Dagzê County at an altitude of 4,300m. Its full name is Ganden Namgyal Ling (dga' ldan rmam rgyal gling). Ganden means "joyful" and is the Tibetan name for Tuṣita, the heaven where the bodhisattva Maitreya is said to reside. Namgyal Ling means "victorious temple".[citation needed]
Samye (Tibetan: བསམ་ཡས་, Wylie: bsam yas, Chinese: 桑耶寺) was the first gompa (Buddhist monastery) built in Tibet. It was probably first constructed between 775-9 under the patronage of King Trisong Detsen of Tibet who sought to revitalize Buddhism, which had declined since its introduction by King Songtsen Gampo in the 7th century. The monastery is in Dranang, Lhoka. It was supposedly modeled on the design of Odantapuri in what is now Bihar, India. The 18th century Puning Temple built by the Qianlong Emperor of Qing China in Chengde, Hebei was modeled after Samye. The original buildings have long disappeared. They have been badly damaged several times — by civil war in the 11th century, fires in the mid 17th century and in 1826, an earthquake in 1816, and in the 20th century, particularly during the Cultural Revolution. As late as the late 1980s pigs and other farm animals were allowed to wander through the sacred buildings. Each time it has been rebuilt, and today, largely due to the efforts of Choekyi Gyaltsen, 10th Panchen Lama from 1986 onward, it is again an active monastery and important pilgrimage and tourist destination.
