Great Prayer Festival
The Great Prayer Festival (Wyl. smon lam chen mo) took place annually in Lhasa until 1959. It was first established by Tsongkhapa Lobzang Drakpa in 1409. Taking place a few days after Losar, it was the most important gathering of the year for the monks of the "three great seats" of Sera, Drepung and Ganden and attracted pilgrims from all over Tibet.
