The Chorten was the place where Lama Lhutsun Chempo created the time capsule by burying all the gifts to mark the occasion.

[2] Norbugang Chorten was established during a consecration ceremony that was held by three learned Lamas headed by Lhatsun Chempo, crowning the first Chogyal of Sikkim.

On this occasion, the Lepchas and Magarsof the area, who had accompanied Phunshog to Yuksom Norbugang for the coronation ceremony, had presented a large number of treasures to the lamas, particularly to Lhatsun Chempo.

They then built the chorten with the materials collected and also buried within it all the gifts that Lhatsun Chempo had received from the people.

[4] The Norbugang Coronation throne, which has the "appearance of an old Olympic Medal Podium" is made of stones, which has been white washed now.
