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. Legend has it that upon seeing the Dzong, invading Tibetan armies remarked that the Dzong was “not on the ground. It is a Sky Dzong” before retreating. In the 17th century it was also essential in defending the province as it withstood several Tibetan attacks that were launched from Tawang in Arunachal Pradesh. It has been the political stronghold of Eastern Bhutan for over 300 years. 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. Radhi village is famous for two things, its rice fields and the skill of its weavers. It is often known as the ‘Rice Bowl of the East’ because of its verdant rice fields that supply most of the grain to eastern parts of the country.
