Inspired by the structure of human DNA, each floor of the 272-million-U.S.-dollar (1 billion-Dirham) tower is rotated by one-point-two degrees to achieve the full 90-degree spiral, creating the shape of a helix.

Dignitaries from diplomatic corps and Corporate Dubai joined the celebrations which closed in a gigantic fireworks display across Dubai's new tower and the Marina night-skyline.

The emirate of Dubai also harbors the world's tallest hotel, the near one-thousand-two-hundred- foot (354.7-meter) tall J.W. Marriott Marquis.

There's also the world's tallest residential tower, the Princess Tower reaching over one-thousand-three-hundred-feet (414 meters), a five-minute walk away from the twisted tower.

Cayan Projects, estimated to be worth around 2.7 billion dollars (10-billion Saudi riyal) cover a wide spectrum of developments from exclusive residential to commercial projects.
