Drugyel dzong or the Fortress of the Victorious Bhutanese was constructed by Zhabdrung Ngawang Namgyal in 1646 to commemorate his victory over marauding Tibetan armies and to guard the Paro valley against further aggressions. Though the fortress was destroyed by fire in 1951 and remained in ruins until restoration efforts began in 2016 commemorating the birth of the Crown Prince Gyalsey Jigme Namgyal Wangchuck. The black top road ends here and continues as a small path to the northern border area of Lingshi, home to yak herders. On clear days, the white peak of Mt. Jomolhari stands out behind its ramparts.
