At the heart of the floating city, a marine institute will be found serving as a living lab and educational facility, but will also be responsible for the construction of the world’s largest artificial reef. Covering an expansive area of 200 square meters, the reef endeavors to create a thriving habitat for over one billion corals and one hundred million mangrove trees, making it the most diverse man-made reef ever to be made.
