History of Trashigang Dzong
Trashigang Dzong was constructed in 1659 after Zhabdrung Ngawang Namgyal instructed Chögyal Minjur Tenpa to establish a fortress that would consolidate political authority and defend eastern Bhutan. Over the following centuries, the dzong was expanded by later rulers, including Gyalsey Tenzin Rabgye and Dzongpon Dopola, strengthening its defensive and administrative functions.
The fortress also played an interesting role following the 1962 Sino-Indian War, when Indian soldiers returning home through eastern Bhutan deposited their rifles at the dzong’s armoury before continuing their journey. Many of those rifles are still preserved there.
Following damage from the 2009 Bhutan earthquake, the dzong underwent major conservation and restoration work to preserve its historic architecture while maintaining its role as a religious and administrative center.
