Drepung Monastery, (literally “Rice Heap” monastery), located at the foot of Mount Gephel, is one of the "great three" Gelukpa university monasteries of Tibet. The other two are Ganden and Sera. Drepung is the largest of all Tibetan monasteries, and indeed at its peak was the largest monastery of any religion in the world. It was founded in 1416 by Jamyang Chojey, a direct disciple of Je Tsongkhapa, the founder of the Gelukpa school. It is located on the Gambo Utse mountain, 5 kilometers from the western suburb of Lhasa. Freddie Spencer Chapman reported, after his 1936-37 trip to Tibet, that Drepung was at that time the largest monastery in the world, and housed 7,700 monks, "but sometimes as many as 10,000 monks."
