Trashigang Dzong, known as the “Dzong of the Auspicious Hill,” is a majestic fortress strategically built in 1659 by the 3rd Druk Desi, Chogyal Minjur Tempa, on a spur overlooking the confluence of the Dangme Chhu and Gamri Chhu rivers. Its imposing location, accessible only from the north, historically made it impenetrable, earning it the nickname “The Fortress of the Eastern Drukpas.” It served as a critical administrative and monastic center, controlling trade routes and defending the eastern frontiers from invaders.

The dzong is a prominent landmark, visible from all directions, and its whitewashed walls and traditional Bhutanese architecture are a testament to the kingdom’s rich heritage. It remains an active monastic and administrative center today, housing a community of monks and government offices. The annual Trashigang Tshechu, a vibrant religious festival, is held in its courtyard, drawing thousands of devotees and tourists, making it a focal point for cultural and spiritual life in eastern Bhutan.
