Hydropolis Underwater Hotel and Resortby Roland Dieterle
- Jumeira Beach, Dubai
The Hydropolis Underwater Hotel and Resort was a proposed hotel, designed by Prof. Roland Dieterle that would be the world's first underwater luxury resort. It was planned to be situated 66-foot (20 m) below the surface of the Persian Gulf, just off Jumeira Beach in Dubai, and projected to cost $300 million to construct. The underwater hotel would have been one of the most expensive hotels on the earth. The hotel was conceived in 2006, was delayed in 2008, and as of June 2010 no construction or planned construction has occurred.
