17th-Century Lead Ingots Recovered at Hornsea 3 Wind Farm Site

Conserved ingots bearing stamps linked to Dutch 17th-century trade will be placed in the Peak District Lead Mining Museum.

Overview

  • Survey crews conducting mandatory pre-construction safety scans for Ørsted’s Hornsea 3 found the wreck and cargo on the seabed about 75 miles east of Norfolk at roughly 131 feet depth.
  • Teams recovered three lead ingots, each about 70–75 kg, that carry stamped marks similar to those on the 1664 Kennemerland wreck and suggest a 17th-century, Dutch-trade connection.
  • Only small timber fragments survived beneath the metal, which leaves the wreck’s exact identity and the ship’s full story unresolved.
  • The ingots have been transferred for conservation and are promised to the Peak District Lead Mining Museum for public display after preservation work.
  • The find highlights how seabed surveys for large offshore projects can reveal long-buried heritage and connects to a known 17th-century trade pattern of Derbyshire lead exports to Dutch ports while Hornsea 3 construction continues on schedule for late 2027.
