They searched for diamonds in the desert – and found a ship with thousands of gold coins

A new study brings back to the headlines one of the most unusual archaeological discoveries found in the Namibian desert: a nearly 500-year-old Portuguese merchant ship, accidentally uncovered in 2008 during diamond mining, containing thousands of gold coins, dozens of tons of metals, and ivory. The study, published this month, examined the efforts to preserve the treasures since their discovery and warns that some of the findings are deteriorating – while the ship and its cargo continue to provide a rare glimpse into the trade network that connected Europe, Africa, and Asia in the 16th century.

The discovery took place in the Sperrgebiet area in southern Namibia, near the town of Oranjemund and the mouth of the Orange River. It is a desert coastal strip, rich in diamonds, access to which was restricted for years due to mining activity. It was precisely in the place where workers expected to find precious stones that they encountered the remains of a Renaissance-era vessel.

Mining work in the area was halted to allow archaeologists to examine the site. As the excavations progressed, the scale of the cargo buried at the site became clear: about 22 tons of copper, more than 2,000 gold coins with a total weight reaching about 23 kilograms, ivory, weapons, and equipment used by the ship's crew.

Some of the copper ingots bore a trident-shaped mark linked to Anton Fugger, a member of a family that operated one of the most powerful banking houses in Europe during the Renaissance. For researchers, these marks were another clue to the vast economic system behind the maritime trade voyages of that period.

Terrain conditions also aided the exceptional preservation. The heavy cargo likely stabilized parts of the ship after the disaster, while layers of sand covered the remains and protected materials that might otherwise have decomposed or disappeared over the centuries that have passed.

One of the central questions was, of course, which ship was found in the desert. No document was discovered that allows for its certain identification, so researchers combined the cargo, coins, and historical records of the Portuguese fleet. According to the main assessment, it is a merchant ship that left Portugal in 1533 on its way to India, under the command of Dom Francisco de Noronha. On board were likely sailors, soldiers, merchants, and other passengers.

The ability to reach a definitive identification is also limited due to an event that occurred more than two hundred years after the sinking. The massive earthquake that struck Lisbon in 1755, along with the tsunami and fires that followed, destroyed much archival material. As a result, some documents that might have provided a final answer regarding the identity of the vessel are missing today.

The gold coins helped narrow down the time range. Among the findings were coins from the period of John III, King of Portugal in the first half of the 16th century. In those years, the kingdom operated long maritime trade routes through which silver, metals, and goods were transported to ports in Africa and the Indian Ocean.

It is precisely the combination of objects that makes the discovery so important archaeologically. Instead of finding a single coin or an object detached from its environment, researchers received a kind of snapshot of a commercial voyage from nearly five hundred years ago: gold and copper ingots from Europe were found alongside African ivory and equipment of a ship that was on its way to the markets of Asia.

What happened to the people who were on board remains a mystery. Among the ship's remains, only a few human remains and personal items were found, so archaeologists raised the possibility that at least some of the passengers and crew survived the initial disaster and managed to reach the shore. However, there is not enough evidence to determine what happened to them afterwards.

Archaeologist Dieter Noli, who has studied the area for years, referred to the harsh conditions prevailing along the coast as part of the discussion on possible scenarios for the sinking. "A winter storm along this coast is no small matter," he said. The exact reason for the loss of the ship, however, is not known with certainty.

At the beginning of the 16th century, Portugal was one of the most important maritime powers in the world. Its ships sailed vast distances and participated in a trade system that linked Europe, the coasts of Africa, and the markets of Asia. The voyages lasted months and involved many dangers, from storms to diseases and maritime accidents.

The finding in Namibia provides researchers with a rare glimpse into this world. The more than 2,000 gold coins are the most attractive part of the discovery, but scientifically, the fact that a diverse cargo was preserved together is especially important. Thus, it is possible to learn which goods were transported between continents and how European funding sources, African resources, and trade with Asia integrated into one system.

The circumstances of the discovery make the story even more unusual. The ship was not located underwater by an archaeological expedition searching for it, but was uncovered during diamond mining in a closed desert coastal area. After the importance of the find became clear, activity in its vicinity was stopped to allow experts to document and remove the objects remaining at the site.

Nearly five hundred years after the sinking, the value of the discovery exceeds the worth of the gold found in it. The ship and its cargo have become a kind of time capsule of a vanished commercial world – a tangible testament to the routes that connected three continents as early as the 16th century, until one voyage ended in the sands of the Namibian desert.
