Niglihawa situated about 9kms away north of Kapilvastu’s headquarter Taulihawa, is important from both traditional and archaeological point. Sobhawati, a place in Niglihawa, is considered to be a birth place of Kanakmuni Buddha. As per Mahakalpa, a grantha, when he was born in a Brahman fanily of Sobhawati nagar, there was a huge rainfall where instead of rain drops, pieces of gold were falling from the sky. Thus, the child was named ‘Kanakmuni’. Fahiyan, a Chinese traveller, has mentioned that Showati naga is situated somewhere north of Chemawati. On the west of Adyapi Niglisagar, there is a pillar built by Samrat Ashoka which has broken down into two pieces. The pond nearby is named Niglisagar after this cigar or ‘Nigali’ (cigar in local language) shaped pillar. When
Samrat Ashoka visited various sacred Buddhist arenas such as Kapilvastu and Lumbini with his Guru, Upagupta during 3rd century BC, he had completed 14 years of ruling and on occasion of this achievement, he constructed more Ashoka pillars, Brahmin lipi reads. On one of the pieces, ‘Om Mane Peme Hu’ a Buddhist mantra is also in scripted.
