Titanic
The Titanic is the world's most famous shipwreck. The White Star Line steamer sank on her maiden voyage in 1912. The Titanic boasted a gymnasium, swimming pools, a squash court and Turkish baths. At 11.40pm on 14 April 1912, the Titanic’s lookout rang the bell three times and said, “Iceberg right ahead”. The Titanic's remains were discovered after a long search in 1985, since then several expeditions have returned to the site and explored the wreck. Below are links to original New York Times articles and links to other Titanic related sites.

Andrea Doria
The Andrea Doria was built at the Ansaldo shipyards in Sestri, Genoa, and was launched in 1951. She had accommodations for 1,241 passengers, and 575 crew. She was luxurious to the last detail of her structure and was considered the flagship of the Italian Line. At 11:22 PM, July 25, 1956, while navigating through a dense fog, under the command of Captain Piero Calamai, the Andrea Doria and the Swedish freighter, Stockholm, collided. This disaster has no logical explanation. It could have and should have been avoided, but radar readings aboard both vessels were misinterpreted.

Mary Rose
Built between 1509 and 1511, the Mary Rose was one of the first ships able to fire a broadside. King Henry VIII, described as, “the fairest flower of all the ships that ever sailed”. The ship marked the transition between the medieval ‘floating castles’ and the sleeker galleons. On July 19 1545,  The heavily laden Mary Rose heeled over in a squall of wind and rapidly capsized, water pouring into the lower gun ports. She went down with more than 90 guns on her decks and only 40 of her 700 crew survived. Salvage work started the same year the great warship sank, raising some guns, yards and sails, but was halted by 1550

Monitor
When John Ericsson conceived his "impregnable battery" he had no idea that it would still be fighting battles a hundred years after his death. In the mid nineteenth century he struggled to have his concepts approved by distinguished industrialists mired in the past. But then came the War between the States, and with war always comes technological advancement and the adoption of previously unacceptable innovations. Word arrived in Washington that the South was building an ironclad ram that could destroy the Union fleet with single-handed impunity. Unwittingly, the CSS Virginia (ex-USS Merrimack) provided the impetus to goad reluctant Northern politicians into funding the construction of an ironclad opponent. Thus the Monitor came into being.
Then came the battle that forever changed the way naval strategists viewed warship design and ship-to-ship engagement. The Monitor and the Virginia fought to a standstill, neither ship inflicting significant damage upon the other. Each was invulnerable to the other and to land-based batteries. Nevertheless, by the end of that year (1862) both ironclads were gone: the Virginia was blown up by her crew to prevent capture, the Monitor foundered in a gale off Cape Hatteras, North Carolina.

Bismarck
The Bismarck was the pride of the German navy. Described by Winston Churchill as, "a terrific ship and a masterpiece of naval construction," she was the length of three football fields. However, the maiden voyage of this German warship was short-lived. In May 1941, after an eight-day chase in the Atlantic, Bismarck succumbed to attack from the British in one of the most dramatic sea battles of the war. Crippled by heavy enemy fire, Bismarck tumbled and slid to a halt on a steep undersea mountain. Only 115 of the 2,200 crew survived.  In 1989, Dr Robert D Ballard and his team finally found Bismarck's remains.

Edmund Fitzgerald
On November 10, 1975, in the most famous shipwreck in Great Lakes history, the Edmund Fitzgerald sank in a treacherous storm on Lake Superior. Thanks to the popular 1976 song by singer/songwriter Gordon Lightfoot, the story of the Edmund Fitzgerald has reached and maintained legendary status. The gigantic ore carrier, at one time the largest ship on the Great Lakes and holder of numerous tonnage records, was caught up in a vicious November storm on Lake Superior and, after hours of battling high winds and 30-foot waves, suddenly disappeared from radar without so much as a single warning or SOS from its captain or crew.

Belgrano
The sinking of the warship Belgrano  is one of the most dramatic and controversial events of the Falklands War. On May 2 1982, HMS Conqueror, the British nuclear submarine, fired two torpedoes at the Argentine warship, General Belgrano. Some 300 men were killed on impact.

Atocha
The Nuestra Senora de Atocha was built in Havana in 1620. She was sunk during a hurricane in 1622. The Atocha was partially salvaged by the Spanish in 1623, but according to John Potter's TREASURE DIVER'S GUIDE, "Before work could be concluded the marker buoy on the wreck was carried away in a storm, and the site was never relocated by the Spaniards."
