In the worst maritime disaster involving a Danish merchant ship, SS Norge ran aground on Hasselwood Rock and sank in the North Atlantic, resulting in more than 635 deaths.

SS Norge was a transatlantic ocean liner that was launched in 1881 in Scotland, and lost in 1904 off Rockall with great loss of life. Her final voyage was from Copenhagen, Kristiania and Kristiansand, bound for New York, carrying passengers many of whom were emigrants. It was the biggest civilian maritime disaster in the Atlantic Ocean until the sinking of Titanic eight years later, and is still the largest loss of life from a Danish merchant ship.

Hasselwood Rock is a skerry 200 metres North of Rockall in the North Atlantic.
