Bouddhanath stupa is the world’s largest stupa, located in the northeastern periphery of Kathmandu about 20minutes drive from the heart of the Kathmandu. The great Stupa of Bouddhanath is the principle center of Tibetan Buddhist worship in Kathmandu valley. It has been a major destination for pilgrims from the Himalayas, Tibet and southeast and east Asia. It is one of the magnificent Buddhist monuments in the world. Bouddhanath was founded by the Nepalese Lichhihavi king Sivadeva through other Nepalese chronicles date into the regin of King Mahendra. The sources claim a mound on the site was excavated in the late 15th or early 16th century and the bones of king Amshuvarma 605-621 were discovered there while other Nepali sources claim it was constructed by a prince to seek forgiveness for unwittingly killing his own father. However the Emperor of the Tibetan Empire Trisongn Destan is also traditionally associated with the construction of the Bouddhanath stupa, after Songsten Gampo was converted to Buddhism by his wives the Nepali princes Bhirkuti and Princess Wen Cheng of China 7th century and passes it on to Detsan. However, given that Kathmandu was invades by the Mughlas in the 14th century who would have destroyed the monument, the current stupa is believed to date to sometime after this. ss
