Boudha is a stupa in Kathmandu, Nepal. Located about 11 km from the center and northeastern outskirts of Kathmandu, its massive mandala makes it one of the largest spherical stupas in Nepal and the world.
The influx of large populations of refugees from Tibet has seen the construction of over 50 gompas around Boudha. As of 1979, Boudha Stupa is a UNESCO World Heritage Site. Along with Swayambhu, it is one of the most popular tourist sites in the Kathmandu area.
The stupa is on the ancient trade route from Tibet which enters the Kathmandu Valley by the village of Sankhu in the northeast corner and continues to the ancient and smaller stupa of Chabahil named Charumati Stupa. It then turns directly south, heading over the Bagmati River to Lalitpur, bypassing the main city of Kathmandu. Tibetan merchants have rested and offered prayers at Boudha Stupa for many centuries. When refugees entered Nepal from Tibet in the 1950s, many decided to live around Boudhanath. The stupa is said to entomb the remains of Kassapa Buddha.
