Punakha Dzong — formally Pungthang Dewa Chhenbi Phodrang, meaning "the palace of great happiness" — is widely regarded as the most beautiful dzong in Bhutan. Built in 1637 by the Zhabdrung Ngawang Namgyal at the confluence of the Pho Chhu (Male River) and Mo Chhu (Female River), the fortress-monastery rises from a tongue of land between the two rivers like a white ship. Its setting is exceptional: jacaranda trees bloom purple against the whitewashed walls in spring, and the reflection of the dzong in the rivers below is one of the iconic views of Bhutan.
The dzong served as Bhutan's capital and seat of government until 1955, when these functions moved to Thimphu. It remains the winter residence of the Je Khenpo, Bhutan's highest religious authority, who moves here from Thimphu each October with some 500 monks. The interior is equally impressive: a series of courtyards, temples, and administrative quarters, decorated with elaborate wood carving and religious murals. The Macchen Lhakhang contains the embalmed body of the Zhabdrung himself, and the main temple holds an enormous Buddha statue. Visitors are welcome but must dress appropriately and are escorted in groups.
