Remember how the 984-foot-long cruise ship Costa Concordia ran aground in Italy in 2012? Now, police divers have re-entered the vessel, days before an attempt to re-float it, and this video shows exactly what it looks like two years on.

This Is What the Sunken Cruise Ship Costa Concordia Looks Like Now

Frozen in time, the ship's shops, staircases, cabins and corridors lie deserted beneath the waves, framed by shredded metal work and covered in silt. Its an eerie reminder of the devastating day when 32 drowned and 4,200 passengers and crew were forced to scramble to safety.

The ship was righted last year but it still needs to be evacuated of water before it can be brought to shore properly. [YouTube]
