Brief History of Trashigang Dzong


The fortress was built in 1659 at top of edge with steep cliffs on three sides, overlooking the Drangme Chhu and Gamri Chhu rivers. The construction of the Dzong was prophesied by Zhabdrung Ngawang Namgyal who ordered the Penlop (Governor) of Trongsa, Chhogyal Minjur Tampa to put down local chieftains and construct the Dzong.  According to legend, the sight of the Dzong scared the invading Tibetan army which retreated while remarking that the Dzong was a " (Nam Dzong) Sky Fortress and was not on the ground". The Dzong was further expanded by Gyalsey Tenzin Rabgye between 1680 and 1694 and by Dzongpon Dopola in 1936. The Dzong was consecrated and named as Trashigang by Dudjom Jigdral Yeshe Dorje. After the 1962 Sino-Indian War, Bhutan allowed Indian soldiers returning home to pass through Eastern Bhutan. However they were required to deposit their rifles at the armory in the Dzong, and proceed through Bhutan unarmed. The rifles lies in the Dzong even today. The Dzong celebrates the four day long Trashigang Tshechu festival every year, with people of fifteen Gewogs.
