Devadaha is the famous ancient capital of Koliya kingdom, the maternal hometown of queen Maya Devi, Prajapati and princess Yasodhara. The site is situated at about 57 km northeast of Lumbini and is well connected by the Mahendra Highway. We can observe many archaeological and historical sites extended in a large area. The potential ancient sites of Devadaha include Kumarvarti, Khayardada, Bairimai-Kanyamai, Bhagawanipur/Devidamar, Kotahimai, the RohiniRiver, the Telar River etc. More facts on ancient Koliyan civilization will reveal after full-fledged excavations in future.
The Koliyas obtained one of the eight parts of the Buddha’s relic which they enshrined here and built a magnificent stupa and worshipped for a long time. Buddhist literary sources mention that Emperor Asoka wanted to open and obtain the Buddha’s relic to build eighty four thousand minors stupas throughout his vast empire. However, the emperor did not touch the precious relic out of the request made by Dragon king and people of Ramagrama. This surviving single original relic stupa standing 7 meters high on the bank of the JharahiRiver is the most important stupa of its kind in the whole of the world.
