Plans are moving forward to build the largest underwater tourism attraction in the world in Dubai: the theme park is set to include scuba diving and snorkeling in a space modeled after the mythical Lost City of Atlantis.

To be developed by the same outfit that has designed sets for blockbuster movies like “Avatar” and “Pirates of the Caribbean,” the Pearl of Dubai is being billed as the largest sustainable underwater tourism site as it will stretch across five acres off the city coast, reported emirates247.com.

Los Angeles-based underwater developer Reef Worlds made the official announcement last week.

“The Reef Worlds brand is all about sustainability and the creation of new habitat while at the same time adding instant tourism revenue and excitement to waterfront resorts,” said Dave Taylor, director of development for Reef Worlds.

“We will work with carefully selected resort partners on unique underwater habitat projects that directly support our clients’ sustainability and revenue goals,” Taylor added.

The underwater attraction will be designed to excite the imagination with submerged ruins and references to a mythical, sunken empire.

The artificial reef, to be built in shallow waters of The World islands, will also aim to foster marine life with colonies of algae and soft corals, reported The National earlier this year when plans were still afoot.

The World is an artificial archipelago of small islands constructed to resemble a world map in Dubai.

Reef Worlds also has its eye on developing the waterfront in the Philippines.

A completion date has yet to be announced.
