RMS Atlantic was a transatlantic ocean liner of the White Star Line that operated between Liverpool, United Kingdom, and New York City, United States.
During the ship's 19th voyage, on 1 April 1873, it ran onto rocks and sank off the coast of Nova Scotia, killing at least 535 people.
It remained the deadliest civilian maritime disaster in the Northern Atlantic until the sinking of SS La Bourgogne on 2 July 1898 and the greatest disaster for the White Star Line prior to the loss of RMS Titanic 39 years later.
There is a burial ground, monument and museum on the shoreline beside the shoal where she sank (a few miles from my home in Nova Scotia). It is very informative and I recommend you visit it if you are in Nova Scotia.
