Dagana Dzong, The Last Dzong Built by Zhabdrung
Dagana Dzong, formerly known as Daga Trashiyangtse Dzong, is one of the 16 dzongs that Zhabdrung Ngawang Namgyal built in Bhutan. In 1651, under Zhabdrung Ngawang Namgyal’s command, Druk Namgyel built it on a ridge overlooking a valley to bring Daga Lungsum under central rule.
