Trashigang Dzong or ‘The Fortress of the Auspicious Hill’ was built in 1659, to defend against Tibetan invasions. This imposing fortress is strategically situated high atop a spur overlooking the Dangmechu River. According to legend it is said that upon seeing the Dzong, invading Tibetan armies remarked that the Dzong was “not on the ground. It is a Sky Dzong” before retreating. It has been the political stronghold of Eastern Bhutan for over 300 years.
Mount Meru is the site of the palace of the Druk Chhoglay Namgyal (victory of Bhutanese Over enemies in all directions). It is accessible only from the north, via a narrow road, paved by blasting through the cliff-side. Due to its location Trashigang Dzong is one of the most strategically placed Dzongs in Bhutan. The present Dzong was enlarged by Dzongpon Dopola, in 1936.
