A warship lost during the Battle of Copenhagen in 1801 has been discovered off the coast of Denmark, marking a significant archaeological breakthrough more than two centuries after it sank. Maritime archaeologists confirmed the find on Thursday, April 3, 2026, following months of underwater excavation in Copenhagen Harbor.

The vessel, identified as the Dannebroge, was located about 15 meters below the seabed during surveys conducted ahead of a planned infrastructure project. The ship sank during the Battle of Copenhagen on Monday, April 2, 1801, when Danish-Norwegian forces faced a powerful British fleet led by Admiral Horatio Nelson.

Archaeologists reported that the ship’s structure closely matches historical records and drawings. The seabed surrounding the wreck is scattered with cannonballs and weapon fragments, offering clear evidence of the intense naval conflict. Two cannons have also been recovered from the site.

The Dannebroge played a central role in Denmark’s defense but was heavily bombarded during the battle, eventually catching fire and exploding. Historical records indicate that at least 56 crew members died, with many others injured.

Excavations have also uncovered personal items such as shoes, clothing fragments, pipes, and uniform pieces, along with human remains believed to belong to crew members. Experts say the discovery provides a rare and powerful insight into one of Denmark’s most significant historical battles.

Researchers describe the find as remarkable, noting that despite the battle’s historical importance, it had never previously been examined through archaeological investigation.
