The dzong is on a high promontory that overlooks the confluence of the Drangme Chhu and the Gamri Chhu. It was built in 1667 by Mingyur Tenpa, Bhutan's third desi. The entire eastern region was governed from this dzong from the late 17th century until the beginning of the 20th century.
This dzong is unusual in that both the administrative and monastic bodies face onto a single dochey (courtyard). As always, the gorikha (porch) has paintings of the Four Guardian Kings.
Inside the Kunrey Lhakhang is a statue of the deity Gasin-re or Yama, the wrathful aspect of Chenresig. He is a protector of the faith, the god of death and the king of law, and the one that weighs up the good and evil at the end of a person's life. You can see him in the vestibule of most lhakhangs holding the Wheel of Life in his mouth. Many lama dances are performed in Trashigang to appease Yama, especially during the four-day tsechu in November/December.
Really appreciate YANA's professional organization of the entire trip. Could not imagine how a trekking trip could such be well organized - more or less like a 5-star hotel with the only difference of we were at more than 3,000 above sea level. Special thanks to Yeshey and the chef who had given tons of assistance when I was descending due to attitude sickness. - Simon Liu, Hong Kong
