The dzong was modeled after the Gyal Gyad Tshel Institute of Ralung (Tibet) and is quite distinctive as its Utse or central tower has 12 sides. A large statue of Yeshay Gonpo (Mahakala) the chief protective deity of Bhutan is housed inside the Utse. Another interesting aspect of the dzong is that it contains the bed chambers of both Zhabdrung Ngawang Namgyel and Jigme Namgyel two of the most important figures in Bhutanese history. Zhabdrung was the leader that first united Bhutan as a nation and Jigme Namgyel was the father of the first King of Bhutan Ugyen Wangchuck.
The dzong houses countless statues and paintings of various Buddhas, deities and religious figures including The Eight Manifestations of Guru Rimpoche, Jampelyang the Bodhisattava of Wisdom, Shakya Gyalpo the Buddha of Compassion and many more, all carved and painted in exquisite detail.
