The dzong hosted a monastic community besides acting as the central administrative center of the Trashigang District, before they were shifted due to the ongoing restoration.

The construction of the dzong was prophesied by Ngawang Namgyal who ordered the Penlop (Governor) of Trongsa, Chhogyal Minjur Tempa to put down local chieftains and construct the dzong.

The dzong was consecrated and named as Trashigang by Dudjom Jigdral Yeshe Dorje.

However they were required to deposit their rifles at the armoury in the Dzong, and proceed through Bhutan unarmed.

The renovation works are expected to be completed by June 2018, while the costs have risen to Nu.227.5 million.
