Standing majestically at the confluence of the Pho Chhu and Mo Chhu rivers, the dzong (fortress) was constructed in 1637-38 and is the second oldest dzong in the Kingdom. The dzong houses the sacred relics of the southern Drukpa Lineage of the Kagyu school of Tibetan Buddhism, including the Rangjung Kasarpani and the sacred remains of Ngawang Namgyal and the terton Pema Lingpa. It was the administrative centre and the seat of the Bhutanese government until 1955, when the capital was moved to Thimphu. Today, it is still the winter residence of the Je Khenpo (Chief Abbot) and the monastic body of Bhutan. Set against a spectacular backdrop, the architecture of the dzong is simply awe inspiring. It was in Punakha dzong that the wedding of His Majesty King Jigme Khesar Namgyel Wangchuck and Her Majesty Queen Jetsun Pema was held on October 13, 2011.
