Dzong (Fortress) symbolizes the presence and recognition of a central authority and sovereignty. Tashichodzong is situated on the bank of the Wangchhu River adjacent to the National Parliament House of Bhutan. Under the command of the Third King the Dzong was renovated extensively in 1962. The entire Dzong was rebuilt without nails or written plans. In the past, the National Assembly met within the Dzong.
Today it houses the Office of His Majesty of Bhutan. Dictated by tradition, the Dzong also houses important government offices and accommodates the state monk body. The Dzong also encompasses many sacred shrines. The open courtyard next to the Dzong observes the popular Thimphu mask dance festival.
