A Danish warship from the 1801 Battle of Copenhagen, the Dannebroge, has been discovered on the seabed in Copenhagen Harbor by marine archaeologists led by Denmark’s Viking Ship Museum.

Finds largely align with historical records in ship size and final position, though underwater conditions are challenging due to poor visibility and sediment.

The wreck provides a tangible link to life aboard a ship under cannon fire, offering fresh insights into the battle beyond traditional accounts.

This marks the first systematic examination of the site, featuring ongoing work, 3D imaging, and an expected completion of investigations in the spring.

The wreck, sunk after a heavy engagement in the 1801 battle, lies beneath thick sediment with near-zero visibility, and divers are documenting it before construction alters the site.

The Lynetteholm project has sparked protests over environmental impacts as testing and digging proceed ahead of construction.

The wreck sits about 15 meters (49 feet) below the surface under thick sediment, with excavation racing to document the site before Lynetteholm development progresses.

The Dannebroge was found at about 15 meters depth during surveys connected to the Lynetteholm project, a planned artificial peninsula intended to shield Copenhagen from rising seas.

Archaeologists hope the finds will illuminate crew personal stories and offer new perspectives on the battle while the dig runs parallel to nearby development for a future urban district by 2070.

Artifacts recovered, including two cannons, uniforms, insignia, shoes, bottles, and a sailor’s lower jaw, shed light on the crew and the ship’s final moments.

The dig is part of a broader effort linked to Lynetteholm construction, with a timeline targeting completion around 2070 and reinforcing Denmark’s national memory of the battle.

Archaeologists aim to piece together crew personal narratives and deepen understanding of the battle’s place in Danish national memory.
