Four kilometres below the surface of the Atlantic Ocean lies the most famous shipwreck in the world.

The Titanic sank on its maiden voyage on April 12, 1912, about 650 kilometres off the coast of Newfoundland.

More than 1,500 passengers and crew died after the supposedly “unsinkable” ocean liner hit an iceberg and sank.

In 2010, scientists used sophisticated equipment to take very detailed photographs of the Titanic and the wreck site.

The photos were “stitched together” to provide an incredible visual record of every centimeter of the outside of the ship. Many of the photos will eventually be shown to the public.
