What was the original date of construction of the fortress destroyed in 1880 by British Indian Troops?
Arg (Kabul) The Arg (Pashto: ارګ‎ ; Persian: ارگ‎ ‎ ; meaning "citadel") serves as the presidential palace in Kabul, Afghanistan. It sits on an 83 acre site in the affluent neighbourhood of Wazir Akbar Khan. The Arg was built after the destruction of the Bala Hissar in 1880 by the British Indian troops. It has been used by many Afghan kings and presidents, from Emir Abdur Rahman Khan to current President Ashraf Ghani.
Svartholm fortress The Svartholm fortress (Finnish: "Svartholman merilinnoitus" ; Swedish: "Svartholms fästning" ) was built between 1749 and 1764 outside Loviisa in Southern Finland by Augustin Ehrensvärd. The fortress, which lies at the mouth of the Bay of Loviisa, along with the planned land fortress at Loviisa, would have prevented invading Russian forces from entering what was then Swedish territory in present-day Finland.
