Boudhanath (also called Bodhnath or Baudhanath or the Khasa Caitya) is one of the holiest Buddhist sites in Kathmandu, Nepal. It is known as Khasti by Newars as Bauddha or Bodh-nath by modern speakers of Nepali. Located about 11 km (7 miles) from the center and northeastern outskirts of Kathmandu, the stupa's massive mandala makes it one of the largest spherical stupas in Nepal.
The Buddhist stupa of Boudhanath dominates the skyline. The ancient Stupa is one of the largest in the world. The influx of large populations of Tibetan refugees from China has seen the construction of over 50 Tibetan Gompas (Monasteries) around Boudhanath. Boudhanath is one of the sites in Nepal listed as UNESCO World Heritage Sites. Along with Swayambhunath, to the western side of the city centre, it is one of the most popular tourist sites in Kathmandu city.
The Stupa is on the ancient trade route from Tibet which enters the Kathmandu Valley by the village of Sankhu in the northeast corner, passes by Boudnath Stupa to the ancient and smaller stupa of Ca-bahi (often called 'Little Boudnath'). It then turns directly south, heading over the Bagmati river to Patan - thus bypassing the main city of Kathmandu (which was a later foundation). Tibetan merchants have rested and offered prayers here for many centuries. When refugees entered Nepal from Tibet in the 1950s, many decided to live around Bouddhanath. The Stupa is said to entomb the remains of a Kasyapa sage venerable both to Buddhists and Hindus.
The Legend of The Construction of Bodhanath Stupa: "The village that surrounds the great Kasyapa tower is generally known by the name of Boddha. ...which in Tibetan is called Yambu Chorten Chenpo. Yambu is the general name by which Kathmandu is known in Tibet; and Chorten Chenpo means great tower. The real name of the tower in full is, however, Ja Rung Kashol Chorten Chenpo, which may be translated into: "Have finished giving the order to proceed with." The tower has an interesting history of its own which explains this strange name. It is said in this history that Kasyapa was a Buddha that lived a long time before Shakyamuni Buddha. after Kasyapa Buddha's demise, a certain old woman, with her four sons, interred this great sage's remains at the spot over which the great mound now stands, the latter having been built by the woman herself. Before starting on the work of construction, she petitioned the King of the time, and obtained permission to "proceed with" building a tower. By the time that, as a result of great sacrifices on the part of the woman and her four sons, the groundwork of the structure had been finished, those who saw it were astonished at the greatness of the scale on which it was undertaken. Especially was this the case with the high officials of the country, who all said that if such a poor old dame were allowed to complete building such a stupendous tower, they themselves would have to dedicated a temple as great as a mountain, and so they decided to ask the King to disallow the further progress of the work. When the King was approached on the matter his Majesty replied: "I have finished giving the order to the woman to proceed with the work. Kings must not eat their words, and I cannot undo my orders now." So the tower was allowed to be finished, and hence its unique name, "Ja Rung Kashol Chorten Chenpo." I rather think, however, that the tower must have been built after the days of Shakyamuni Buddha, for the above description from Tibetan books is different from the records in Samskrt, which are more reliable than the Tibetan."
