Uronarti, a Nubian word meaning "Island of the King", is an island in the Nile just south of the Second Cataract in the north of Sudan. The primary importance of the island lies in the massive ancient fortress that still stands on its northern end. This fortress is one of a number constructed along the Nile in Lower Nubia during the Middle Kingdom (19th century BC), primarily by the rulers Senusret I and Senusret III. Read more on Wikipedia
