As per the Assam Gazetteer (1928), the pillar was found between the Dibang and Deopani rivers, on the eastern side close to the seventh milepost of the road from Sadiya to Nizamghat.

[2][3] The British explorer S. F Hannay found a brick gateway, stone bridge and a brick tank in the same region (between the Dibang and Deopani rivers), but fortified by tall ramparts.

Ahoms who captured Sadiya in 1523 and entered into a treaty with the local Mishmi tribe, the terms of the treaty were inscribed on an eleven feet high stone pillar, constructed in a design of a huge serpent encircling it from bottom to top.

[7] The epigraph consisting 9 and a half lines on the pillar is a proclamation issued by Phrasenmung Borgohain (Ahom governor of Sadiya) asking the Mishimis to pay annual tribute in certain articles and to dwell on one side of the Dibang River.

[9] It was removed from its original site in 1953, and placed in Assam State Museum and since then has been in display there.
