Azerbaijan Tower is a proposed supertall skyscraper to be constructed on the Khazar Islands, 25 km (16 mi) south of Baku, Azerbaijan. The $3 billion tower is to be the centerpiece of the Khazar Islands, a $100 billion city of 41 artificial islands that will spread 3,000 hectares over the Caspian Sea. The city will be equipped with 150 bridges and a large municipal airport to connect the islands to the mainland. [Wiki]
