Сонгцэн Гампо
The site, which is over 1,300 years old, dates back to Songtsän Gampo, the founder of the Tibetan Empire, and was amongst the first buildings built in the Lhasa area by him during the 7th century after settlement. Although originally the site of his castle or fort, the "Tibetan Annals" have revealed that Pabonka was converted into a monastery, possibly under the reign of the second great Buddhist king of Tibet Trisong Detsen. Detsen, along with Guru Rinpoche and the first seven monks of the new Tibetan Empire used to meditate at the hermitage and it became one of Tibet's very earliest Buddhist monasteries, possibly even pre-dating Jokhang.
