Tradruk Temple (Tibetan: ཁྲ་འབྲུག་དགོན་པ།, Wylie: khra-’brug dgon-pa, Lhasa dialect IPA: ʈʂʰaŋʈʂuk kø̃pa, referred to as Changzhu Monastery in Chinese) in the Yarlung Valley is the earliest great geomantic temple after the Jokhang and some sources say it predates that temple.
Tradruk Temple is located in Nêdong County of Lhoka in the Tibet Autonomous Region, about seven kilometres south of the county seat, Tsetang.
Tradruk is said to have been the second of Tibet's earliest great geomantric temples after the Jokhang, and some sources even place it earlier. Under the rule of Trisong Detsen (755–797) and Muné Tsenpo, Tradruk was one of the three royal monasteries.
During the persecution of Buddhism under Langdarma (Wylie: glang dar ma, 841–846) and during the Mongol invasion from Dzungaria in the 16th century, the monastery was heavily damaged.
In 1351, Tradruk was restored and enlarged; during the reign of the 5th Dalai Lama (1642–1682), the monastery got a golden roof and under the 7th Dalai Lama (1751–1757), it was further expanded. In the late 18th century, Tradruk is said to have had 21 temples.
Several buildings were destroyed during the Cultural Revolution. During the 1980s, the monastery was renovated and in 1988 it was reconsecrated. Today, the complex has an area of 4667 square metres and is under national protection.
Tradruk is a stop on the Yarlung pilgrimage route called "three sanctuaries, three chortens."
