Costa Concordia victims mark 1 year anniversary

GIGLIO, Italy

During a Sunday tribute, officials unveiled a memorial plaque with the names of the victims and held a mass in their honor.

They also returned to the sea a piece of the rock that was wedged into the ship.

The Concordia remains on its side. Officials say it could take until September to prepare the ship to be turned upright and towed from the rocks to be dismantled.

The cost to remove the ship has swelled to $530 million.

While Sunday's commemoration was focused on the relatives of those who died, Giglio's residents were also being remembered for having opened their doors to the survivors who came ashore that night, cold, wet and traumatized after a chaotic evacuation. Many survivors have stayed in touch with their Giglio hosts, connected in ways they never expected.
