Ancient Shipwreck Discovered During Construction of World’s Largest Offshore Wind Farm

Construction of what is slated to be the world’s largest offshore wind farm, Denmark’s Hornsea 3, has been accompanied by an unexpected historical find: a 17th-century shipwreck. During seabed surveys in the North Sea, marine archaeologists stumbled upon a vessel carrying a significant cargo of lead ingots.

The discovery occurred approximately 120 kilometers off the coast of Norfolk, England, at a depth of about 40 meters. Initial seabed safety assessments, conducted by the energy company Ørsted, were focused on identifying potential unexploded wartime ordnance when the anomaly was detected.

Unexpected Cargo

The survey monitors revealed three lead ingots, each weighing approximately 70 kilograms, still stacked in their original positions on the seafloor. Remnants of the ship’s wooden structure and hull were also visible. The ingots bear distinct marks from their smelter, which are crucial for potentially tracing their origin and the vessel’s trade route. Preliminary analysis suggests a link to Derbyshire, England, a historic lead-mining region.

Historical Significance

This find provides tangible evidence of the English lead trade during the early modern period. The shipwreck’s location places it directly on a historical maritime route connecting Hull, England, with the Netherlands across the North Sea.

During the 17th century, England, particularly the Peak District and Derbyshire, was a major producer of lead. This metal was extensively used for various applications, including pipes, cookware, and weaponry, before its toxic properties were fully understood. Transporting lead in ingot form facilitated its trade as a commodity.

Contextual Regulations

The discovery also underscores the importance of archaeological surveys mandated by heritage legislation in the United Kingdom before major infrastructure projects, especially in marine environments. Similar archaeological requirements have led to other significant finds in recent years, including a Roman anchor at a different British offshore wind farm site.

Preliminary Investigation

The ingots recovered bear three specific engraved marks: “IS,” “EB,” and “H.” These markings bear resemblance to those found on the Kennemerland, a Dutch East India Company ship that sank in 1664 near the Shetland Islands. Based on this similarity, the research team currently hypothesizes that the vessel was likely Dutch and was en route back to the Netherlands with its lead cargo.

However, researchers emphasize that these are preliminary findings. Further in-depth investigation is required to definitively determine the ship’s origin and establish a more precise dating beyond the 17th century. Analytical confirmation of the lead’s geological origin is also pending.
