The Citadel of Herat (Persian: ??? ?????; Pashto ?????? ???); also known as the Citadel of Alexander; and locally known as Qala Iktyaruddin (Persian: ???? ????????????); is located in the center of Herat in Afghanistan. It dates back to 330 BCE; when Alexander the Great and his army arrived to what is now Afghanistan after the Battle of Gaugamela. Many empires have used it as a headquarters in the last 2;000 years; and was destroyed and rebuilt many times over the centuries.

This historic citadel was saved from demolition in the 1950s; and was excavated and restored by UNESCO between 1976 and 1979. From decades of wars and neglect; the citadel began to crumble but in recent years several international organizations decided to completely rebuild it. The National Museum of Herat is also housed inside the citadel; while the Afghan Ministry of Information and Culture is the caretaker of the whole premises. Pictures From History
