The Ajyad Fortress was an Ottoman citadel which stood on a hill overlooking the Grand Mosque of Mecca, in what is now Saudi Arabia. Built in the late 18th century, it was demolished by the Saudi government in 2002 for commercial development of the Abraj Al Bait, sparking outcry from Turkey and other concerned Muslims of the world.
