Danish archaeologists recently unveiled a major historical breakthrough. They found the remains of the world's largest cog ship in the waters off Copenhagen after some 600 years.
The announcement, made by the Viking Ship Museum in Roskilde in late December, noted the ship was found in the Øresund, a strait between Denmark and Sweden.
Divers found the cog — a type of medieval cargo ship — during seabed surveys ahead of construction on Copenhagen's Lynetteholm development.
"From the very first dive, the maritime archaeologists sensed they had uncovered something extraordinary," the Viking Ship Museum said in a statement.
"And as they removed centuries of sand and silt, the outline of a remarkable find emerged. Not just any wreck, but the largest cog ever discovered — a ship that represents one of the most advanced vessel types of its time and the backbone of medieval trade."
