Drepung Monastery, located just outside Lhasa, is one of the 'Four Great Monasteries' of Tibetan Buddhism and was once the largest monastery in the world, housing over 10,000 monks. Founded in 1416 by Tsongkhapa, the founder of the Gelug school, it played a central role in shaping Tibetan religious and political life. The monastery’s iconic golden roofs and sprawling complex of temples, assembly halls, and monk residences are set against the dramatic backdrop of Mount Gephel. Visitors can witness daily rituals such as chanting ceremonies, debates among monks, and colorful masked dances during festivals like Losar (Tibetan New Year). Its historical significance lies not only in its spiritual importance but also in its role as a center for Buddhist scholarship, where monks studied philosophy, medicine, and astrology. For travelers, visiting Drepung offers a profound insight into Tibetan culture—its devotion, discipline, and artistic expression. It is recommended to visit early in the morning for a peaceful experience and to see the monks in their daily routines. Respectful attire and quiet demeanor are essential to honor the sacred environment.
