Built in the 1930s, Mongar Dzong is one of Bhutan’s newest dzongs. It is unique because it has two entrances and because the monk and administrative bodies share the same courtyard. The dzong was built to replace the original Zhongar Dzong. Every November, the week-long Mongar Tsechu is held here. This dzong serves as the administrative and religious center of the district and is a significant landmark, offering insights into local governance and religious practices.
