Sera Monastery (色拉寺) is one of the 'great three' Gelukpa university monasteries of Tibet. The other two are Ganden Monastery and Drepung Monastery. The origin of the name 'Sera' is not certain, but it may derive from the fact that the original site was surrounded by 'Wild Roses' (se ra in Tibetan). Sera was founded in 1419, by Jamchen Chojey (Sakya Yeshe), a disciple of Tsong Khapa.
