Locally known as the Tashi Thongmon Dzong, the fortress served as a defending barrack in the 17th century. It was named after the region’s protecting deity Tashi Thongmon.
The fortress is unique with a circular shape and three watch towers that are placed at strategic points. The beauty of the dzong is heightened during clear days with a view of Mt. Gangboom. Time your trip there during the annual autumn festival.
