Ibrahim Palace, also known as Qasr Ibrahim, is a historic fort in Hofuf, Al-Ahsa, Saudi Arabia, built in 1556 during Ottoman rule. This architectural masterpiece blends Islamic and military styles, featuring semi-circular arches, domes, and a mosque with a distinctive minaret. Originally a military barracks, it later served as a castle, prison, and administrative center, and was seized by King Abdulaziz Al Saud in 1913. Now a UNESCO World Heritage site, it is a key cultural landmark open to tourists.
