Punakha Dzong.

Punakha Dzong, an iconic palace and fortress dating back to the 17th century, is located at the confluence of the Pho Chhu and Mo Chhu rivers in Bhutan. Built by Zhabdrung Ngawang Namgyal in 1637-38, it served as the religious and administrative center of Bhutan until the mid-1950s. The dzong showcases stunning traditional Bhutanese architecture, featuring towering white walls, cantilevered roofs, and intricate woodwork—all constructed without nails. It is one of the most sacred dzongs in the country, housing important relics and serving as the winter residence for the central monastic body. With its breathtaking surroundings, vibrant festivals, and rich cultural heritage, Punakha Dzong remains a crucial landmark for both locals and visitors drawn to Bhutan's history and spirituality.
