This is an image of Bahrain Fort built in the 1500s by the Portuguese. Bahrain is an island nation just 25 km. along a causeway from Saudi Arabia. The fort was built right on top of ruins that date from 2200 BC when Bahrain was known as Delmon by the Babylonians and Mesopotamians. You can make out some of these ruins in the lower right. Later around 300 BC, Bahrain was known as Tylos by Alexander the Great.
