Boudhanath Monastery, Nepal’s largest monastery, is located east of Kathmandu. It is one of the most important pilgrimage sites in the world. Boudhanath Stupa is one of Nepal’s most holy sites for the Buddhist faith. This stupa, a well-known Buddhist pilgrimage site, is included in World Heritage Cultural site list by UNESCO. After the Chinese invasion in 1959, Tibetans in thousands came to this famous Buddhist Chaitya and energized the Stupa.
