Daga Dzong is the headquarters for district administration and houses the clergy. The Dzong used to be the office of the Daga Penlop who held the rank of cabinet minister under the Desi (temporal ruler) system of government introduced by the Zhabdrung. Zhabdrung managed to unify most of western Bhutan by mid-17th century but the central, eastern and southern parts still remained so he deputized Dronyer Druk Namgyel to bring the area under Drukpa rule. Thus, the Dronyer starting constructing the dzong in 1949. Two years later it was completed.
