The Kandahar Citadel, also known as Arge-Kandahar, is a historical fortress located in the city of Kandahar, Afghanistan. This imposing citadel has stood as a symbol of power and defense for the region, with its origins dating back to the time of Alexander the Great. However, the present structure largely owes its form to the 18th-century renovation during the reign of Ahmad Shah Durrani. Positioned strategically in Afghanistan's second-largest city, the Kandahar Citadel has been a vital military stronghold and has witnessed numerous battles throughout its history. Its high walls and sturdy battlements reflect the traditional military architecture of the time. Despite suffering damage during various periods of conflict, the fortress remains an important historical and cultural monument, embodying the rich legacy of Kandahar's past rulers. Although in need of preservation and restoration, the citadel continues to attract both visitors and history enthusiasts who are keen to observe its architectural grandeur and its significance to Afghan heritage.
