Along the Caspian Sea near Baku, Azerbaijan, crews have begun work on a billion city of artificial islands dubbed the Khazar Islands.
The massive, 2,000 hectare project is the first of its kind in the region, and will consist of over 40 man-made islands connected with suspension bridges (66 of them), pedestrian walkways, and innovative infrastructure. The floating metropolis will be home to more than one million people upon its projected completion in 2022, though many residents will be able to move in as soon as first housing blocks are ready.
