Trashigang Tshechu in Trashigang
Trashigang Dzong, built in 1659 on a cliff above the Drangme Chhu and Gamri Chhu confluence to guard Bhutan's eastern frontier, is among the country's largest dzongs and anchors a three-day tshechu with a strongly local, less internationally touristed character than western Bhutan's festivals. It often marks a natural final or opening stop for travelers crossing the full length of the country.
Trashigang Dzong perches on a cliff above the confluence of the Drangme Chhu and Gamri Chhu rivers, built in 1659 by Chogyal Minjur Tenpa to guard the eastern approaches into Bhutan against incursions from Tibet and Assam, and it remains the largest dzong in the country by some measures of enclosed courtyard space.
