Shipwrecks Gallery: Secrets of the Deep

Resting in the Murky Deep

Built in Northern Ireland in 1909, the "RMS Titanic" was also known as the "unsinkable ship," because it had a double-bottom hull divided into 16 compartments that were presumed to be watertight. The 882.5-foot-long (268.9 meters) craft sank in April 1912 after it struck an iceberg off southern Newfoundland, and now rests on the ocean floor at a depth of 12,460 feet (3.7 kilometers).
