Britannia, sunk in 1826 off South Africa

On an outbound run to India, the 460-ton Britannia hit an uncharted reef (now known as Britannia reef) and sank on October 22, 1826, in a part of St. Helena Bay that is now known (appropriately enough) as Britannia Bay. The site was found and salvaged in 1997-1998, its artifacts remarkably well preserved by sand burial, some of its bottles still containing their original liquids and foodstuffs.
