Divers Searching for a Gas Pipeline Route Discover a 400-Year-Old Shipwreck in Germany

A routine underwater survey in northern Germany has led to the discovery of a previously unknown shipwreck dating back roughly 400 years.

The wreck was found in the Bay of Greifswald in 2023, when divers were investigating underwater obstacles ahead of construction work for a gas pipeline. Instead of ordinary debris, they encountered wooden ship remains, anchors, shoe soles and other objects from the vessel.

A Ship Hidden Beneath the Baltic Waters

The wreck lies about 7.5 meters below the surface in soft, silty seabed. Only fragments of the wooden hull survived, but the remaining pieces were enough for archaeologists to identify the vessel as a clinker-built ship.

In this construction technique, overlapping wooden planks are fastened together with iron nails. Gaps between the planks were sealed using materials including tar and animal hair.

A Race Against Construction

Archaeologists had only a short time to investigate the wreck because dredging work for the pipeline was approaching.

A team of five researchers completed 22 dives in just over 12 days. Poor underwater visibility made the work particularly difficult because movement on the soft seabed quickly stirred up the sediment.

More Than 60 Objects Recovered

The rescue excavation produced more than 60 objects connected to the ship and its crew.

Among the discoveries were two iron anchors, rope, barrel pieces, shoe soles, pulley components and a large hollowed-out oak trunk that was probably used as a bilge pump.

Researchers also found carpentry tools, including drill bits and chisels. These objects suggest that the crew may have been able to carry out repairs during long voyages.

Tree Rings Reveal the Ship’s Age

Scientists used dendrochronology, a method that compares tree-ring patterns, to date the wooden remains.

The analysis showed that at least one of the trees used to build the vessel was cut down between 1626 and 1639, placing the ship in the early seventeenth century.

A Mystery That Remains Unsolved

Archaeologists have not yet determined exactly what happened to the vessel. Some of the surviving timbers show traces of fire, while the presence of anchors and other equipment suggests that the ship may have been anchored when it was lost.

Because so little of the hull survived, researchers cannot currently identify the ship or establish the precise circumstances of its sinking.

A Time Capsule of Maritime Life

After the investigation, the pipeline route was changed and the remaining wreck was covered with protective sandbags.

Researchers hope the site can be examined again in the future. Even though only fragments remain, the objects recovered from the seabed provide a rare glimpse into the equipment, working life and technology of sailors in the Baltic region around four centuries ago.
