عبد الرحمن خان
The foundation of the Arg was laid by Emir Abdur Rahman Khan in 1880 after assuming the throne. It was designed as a castle with water-filled trench around it. Abdur Rahman Khan named it "Arg-e-Shahi" (Citadel of the King) and included among other buildings a residence for his family, army barracks, and the national treasury. Previously, the Bala Hissar served as the citadel or the headquarters of the emirs until it was destroyed by the British Indian troops during the Second Anglo-Afghan war (1878–80).
