Years ago, we wrote about an amazing underwater hotel planned for the Maldives. As with so many buildings that demand ingenuity and skill to construct, it has taken a while, but is finally opened to the public, as part of the Conrad Maldives Rangali resort.
The two-storey construction was built (on land) in Singapore then transported to the Maldives by ship. Once lowered into the water, it was secured into place with concrete pylons to prevent shifting in rough waves or at high tide.
