With plans to become the world’s tallest building at about 3645 feet, the Azerbaijan Tower is being built on a series of artificial islands, the Khazar Islands, in the Caspian Sea 16 miles south of Baku, Azerbaijan. Avesta Group, the company behind the project, is expecting to have the skyscraper completed by 2019 at an estimated cost of $2 billion. With 189 floors, it is expected to surpass the the Burj Khalifa Tower in Dubai and Saudi Arabia’s proposed 3280 foot Kingdom Tower. More images can be viewed after the break.
