The Costa Concordia is an Italian cruise ship that collided with an underground rock causing it to sink off the coast of Tuscany in January of 2012. 32 people lost their lives that day and is known as the largest passenger shipwreck to date. The ship was carrying 4,252 people and was on its first leg of a cruise around the Mediterranean Sea starting from Civitavecchia in Lazio, Italy. Costa Concordia went off the planned route at Isola del Giglio and it came too close to the island and hit a rock underneath the water which was heard and felt by the passengers and caused a temporary blackout on the ship.
The Costa Concordia is one of the largest ships ever to be abandoned. There were immediate fears of oil pollution from the wreck. However, there were no serious oil leaks.
Nuestra Senora de las Mercedes (Our Lady of Mercy)
The Nuestra Senora de las Mercedes was a Spanish navy frigate which the British sunk off the coast of Portugal in 1804 during the Battle of Cape Santa Maria. A single shot from the HMS Amphion hit the ship causing an explosion and the ship sank. 250 crewmen lost their lives and 51 survivors were rescued from the sea. The Odyssey Marine Exploration found approximately 500,000 gold and silver coins in the same area as the shipwreck and the total estimated value of the coins is $254 million making the Nuestra Senora de las Mercedes the most valuable shipwreck in the Atlantic Ocean. Accordingly to many historical accounts, the ship was carrying about 4.5 million gold and silver pesos along with vicuna, cinnamon and quinoa.
