Sera Monastery, officially known as "Sera Mahayana Monastery," is located at the foot of Sera Utse Mountain in the northern suburbs of Lhasa. It is one of the six principal monasteries of the Gelug school of Tibetan Buddhism, and along with Drepung Monastery and Ganden Monastery, is considered one of the three great monasteries of Lhasa. Construction began in the 17th year of the Yongle reign of the Ming Dynasty by Tsongkhapa's disciple Shakya Yeshe and was completed in 1434. The monastery houses the Tsokchen Hall, three large datsangs, and other buildings, housing tens of thousands of Buddha statues and numerous murals. Its unique Buddhist debates make it a vital venue for understanding Tibetan Buddhist culture.
