Archaeologists discover wreck of Danish warship sunk by Nelson 225 years ago

Divers in race against time to unearth wreck of the Dannebroge before seabed becomes construction site

More than 200 years after being sunk by Admiral Horatio Nelson and the British fleet, a Danish warship has been discovered on the seabed of Copenhagen harbour by marine archaeologists.

Working in thick sediment and almost zero visibility 15 metres (49 feet) beneath the waves, divers are in a race against time to unearth the 19th-century wreck of the Dannebroge before it becomes a construction site in a new housing district being built off the Danish coast.
