On April 14th, 1912, only four days into her maiden voyage, the RMS Titanic struck an iceberg and sank in the north Atlantic en route from Southampton to New York City. Then the largest passenger ship ever built, she was dubbed “unsinkable” by the press. 1,517 passengers and crew went down with the ship, making it one of the worst maritime disasters in history and an enduring fascination.
