Keutsang Hermitage is a historical hermitage, belonging to the Sera Monastery, about 8 kilometres (26,000 ft) northwest of Lhasa in Tibet Autonomous Region. The hermitage was in a precariously perched cave once inhabited by the great Tibetan guru Tsongkhapa. However, the original cave collapsed in a landslide. What is present now was rebuilt, adjoining the ruined Keutsang West Hermitage, at a safer location. As it exists now, Keutsang is to the east of Sera on a hillside above Lhasa’s principal cemetery. Rakhadrak Hermitage is above and close to this hermitage.
The Sera Monastery is one of the "great three" Gelug university monasteries of Tibet, located 1.25 miles (2.01 km) north of Lhasa and about 5 km (3.1 mi) north of the Jokhang.
The other two monasteries are Ganden Monastery and Drepung Monastery.
The origin of the Sera Monastery is attributed to a fact that during its construction, the hill behind the monastery was covered with blooming wild .
