A deep-sea shipwreck in Norway, archaeologists call the “Porcelain Wreck,” has revealed hundreds of pieces of Chinese porcelain cargo and other luxury goods, offering a rare glimpse into trade networks that connected Europe and Asia during the 18th century.

The wreck was discovered about 600 meters (nearly 2,000 feet) below the surface in the Skagerrak, the body of water between Norway, Denmark, and Sweden. Researchers say the vessel and its cargo are among the best-preserved maritime finds ever recorded in Northern Europe.

Discovery beneath the seabed

The find began in September last year when professional diver Espen Saastad was conducting a routine seabed survey off the Norwegian coast. During a review of underwater footage, he noticed a shipwreck surrounded by stacks of porcelain resting on the seafloor.

The footage was sent to the Norwegian Maritime Museum, where researchers immediately recognized its significance.

“We thought it was an incredible wreck,” said Sven Ahrens, research director at the museum. “We often find cargo and freight, but it’s usually broken or covered by marine growth. Here, whole plates were lying in stacks on the seabed.”

Museum experts identified the cargo as 18th-century Chinese porcelain. The footage also revealed fragments of chandeliers, fine stemware, and other luxury items.

Rare evidence of global trade

Researchers believe the vessel was likely a galiot, a small cargo ship that operated within Northern Europe. While the ship probably never traveled to Asia, the Chinese porcelain cargo likely arrived through major trading centers such as Amsterdam, Copenhagen, or Gothenburg before being loaded onto the vessel.

The discovery provides evidence of the expanding trade networks and growing consumer culture that transformed Europe during the 18th century.

Unlike many shipwrecks found off the Norwegian coast that carried a single commodity, such as timber, fish, or iron, this vessel transported a diverse cargo of imported goods.

“The Porcelain Wreck is the first wreck we have found that demonstrates the breadth of interregional commercial activity in Northern Europe during the 18th century,” said maritime archaeologist Frode Kvalø, who leads the project.

Technology helps recover artifacts

Archaeologists have explored the wreck using a remotely operated vehicle, or ROV, controlled from a research vessel on the surface. The technology allowed researchers to create a detailed 3D model of the site and map the location of the ship and its cargo.

In May, the team recovered nearly 40 artifacts using a robotic arm equipped with specially designed suction cups. Most of the recovered objects were pieces of Chinese porcelain that appeared almost untouched despite spending centuries underwater.

One recovered brick from the ship’s galley carried a maker’s mark linked to Lübeck, Germany. Researchers are now examining historical Danish Sound Dues records in hopes of identifying the vessel and reconstructing its final voyage.

Thousands of artifacts remain

Only a small portion of the cargo has been recovered so far. Thousands of artifacts remain on the seabed, including unopened crates whose contents are still unknown.

Researchers hope the next phase of the project will involve a full archaeological excavation of the site. Such an effort could provide unprecedented insight into maritime trade, shipping practices, and daily life during a period when global commerce was rapidly expanding.

For archaeologists, the shipwreck of Norway represents more than a remarkable collection of Chinese porcelain. It offers a rare and largely untouched snapshot of the commercial world that linked continents centuries ago.

Tourists stand in line under the summer sun outside Notre Dame Cathedral, waiting to climb the landmark and see its famous Roman artifacts. Just a few meters below them, archaeologists are digging into nearly 2,000 years of Parisian history.

The excavation is taking place beneath the cathedral’s forecourt as part of a project to redesign the square. Paris plans to add trees, shade, and cooling features around Notre Dame following its restoration after the devastating 2019 fire. Before work can begin, archaeologists must investigate and protect any remains buried underground.

French media have dubbed the project the “dig of the century” because of the discoveries emerging from one of the city’s most historic locations.

“It’s a rare opportunity for us to work on something that’s tangibly going to make a difference to the history of Paris,” Lucie Altenburg, a conservator with the Paris archaeology unit, told The Associated Press.

Ancient artifacts emerge

Researchers have already recovered hundreds of artifacts. One of the most important finds is a fourth-century coin depicting Roman Emperor Constantine. The coin was heavily corroded when it was unearthed, but X-ray imaging revealed the emperor’s portrait. Such finds help archaeologists date the different occupation layers beneath the cathedral.

The team has also uncovered fragments of medieval pottery marked with faint reddish inscriptions painted on the inside. Similar symbols appear on multiple shards, but experts have not yet determined their meaning.

Some of the most remarkable discoveries have come from medieval latrines buried beneath houses that once crowded the area around Notre Dame. The pits served as both toilets and rubbish dumps, creating conditions that preserved everyday objects for centuries.

Archaeologists have recovered complete jugs, cups, and other ceramics that survived intact after spending hundreds of years underground. It is “rare to find complete ceramics,” said archaeologist Valentine Breloux.

Clues to Paris’ evolution

The excavation has also revealed evidence of Paris’ transformation from the Roman city of Lutetia into the medieval capital that followed.

Archaeologists discovered a Roman stone doorstep that had been removed from a larger building, turned upside down, and reused as paving in a later roadway. The find shows how residents repurposed materials as the Roman world gave way to a new era.

Once artifacts leave the site, they are transported to the city’s archaeology center, where specialists clean, catalog, and study them.

Looking deeper into the past

The work is expected to continue as Paris moves forward with plans to plant 160 trees and create a cooler, greener public square by 2028. Archaeologists hope to dig even deeper before then, searching for traces of the Gauls, the people who inhabited the area before the Roman conquest.

“The hope is that we are able to go back in time even further than we’ve ever been before,” Altenburg said.
