Marine archaeologists have identified the wreck of the Danish battleship Dannebroge, lost during the Battle of Copenhagen in 1801, in waters just outside the Danish capital.
Dannebroge explodes during the Battle of Reden
The discovery, announced by the Viking Ship Museum, confirms the location of one of Denmark’s most historically significant warships, more than two centuries after it was destroyed during the naval battle on 2 April 1801.
The Dannebroge served as a Danish flagship during the battle, part of the wider conflict between Denmark-Norway and the British Royal Navy. During the engagement, the ship caught fire under heavy bombardment before eventually exploding, with heavy loss of life.
A long-lost wreck identified
Marine archaeologists located the wreck in the Øresund, near Copenhagen, following detailed surveys of the seabed. The remains were identified through a combination of structural features and artefacts consistent with early 19th-century naval construction.
Finds from the site include timbers, cannon elements and other material linked to the ship’s final moments, helping to confirm its identity.
The wreck lies in relatively shallow waters, an area that has been subject to both natural processes and centuries of maritime activity, complicating earlier efforts to locate it.
Battle of Copenhagen
The loss of the Dannebroge occurred during the Battle of Copenhagen, when a British fleet under Admiral Horatio Nelson attacked the Danish defensive line.
The battle is one of the most famous naval engagements of the Napoleonic era, and the destruction of the Dannebroge became one of its defining episodes.
Historical accounts describe how the ship continued to fight despite being engulfed in flames, before a catastrophic explosion brought the action to an end.
Maritime heritage
Archaeologists say the discovery provides a rare opportunity to study a well-documented naval battle through physical remains on the seabed.
The wreck is expected to contribute to a better understanding of naval warfare, ship construction and life aboard warships at the beginning of the 19th century.
It also highlights the continuing importance of underwater archaeology in uncovering and preserving maritime heritage sites that remain hidden beneath busy coastal waters.
