The literary meaning of Simtokha is ‘Atop of Demon’ and the Dzong was built by the Gyal Gyad Tshel Institute of Ralung (Tibet). The Dzong looks quite distinctive as its central tower has 12 sides. It houses a large statue of Yeshay Gonpo, the main protective deity of Bhutan. It contains the bed chambers of both Zhabdrung Ngawang Namgyal and Jigme Namgyal, two most important figures in Bhutanese history.
