The Fortress of Van is a massive stone fortification built by the ancient kingdom of Urartu during the 9th to 7th centuries BC, and is the largest example of its kind. It overlooks the ruins of Tushpa, the ancient Urartian capital during the 9th century, which was centered upon the steep-sided bluff where the fortress now sits. A number of similar fortifications were built throughout the Urartian kingdom, usually cut into hillsides and outcrops in places where modern-day Armenia, Turkey and Iran meet. Successive groups such as the Medes, Achaemenids, Armenians, Parthians, Romans, Sassanid Persians, Byzantines, Arabs, Seljuks, Safavids, Afsharids, Ottomans and Russians each controlled the fortress at one time or another. The ancient fortress is located just west of Van and east of Lake Van in the Van Province of Turkey.
