More than two and a half years since it crashed near Isola del Giglio, Italy, the wreck of the Costa Concordia was successfully refloated this week, and has begun its final journey—a four-day trip to a scrap yard in Genoa.

The cruise ship capsized after striking a reef on January 13, 2012, killing 32 passengers and crew members. The complex salvage operation was the largest and most expensive in history.

The wreck of the Costa Concordia cruise ship was refloated using air tanks attached to its sides.
