The 6,825-ton passenger ferry Sewol (built 1994) sank on 16 April 2014 off the coast of South Korea in a tragedy that claimed 304 lives, most of which were high school children on an educational trip.
Just prior to the anniversary, the wreck was last week returned to the port of Mokpo.
It marked the completion of the remarkable and near-two-year-long wreck-removal operation.
