Cleopatra’s Tomb: Sunken Harbour Near Taposiris Magna Offers New Clues

For two millennia, scholars have wondered where Egypt’s last queen was laid to rest. Now suspicion is growing that the trail to Cleopatra’s legendary tomb may begin beneath the water, close to a long-underestimated temple west of Alexandria.

A sunken harbour reshapes the search

On 18 September 2025, Egypt’s Ministry of Tourism and Antiquities announced a discovery that initially sounded like a conventional case of underwater archaeology: an ancient harbour had been identified near the Mediterranean coast, now buried several metres below sea level.

Announcements of this kind are not unusual in Egypt, a country whose history is central to its identity. Yet the location immediately caught experts’ attention. The harbour remains lie only a few kilometres from Taposiris Magna, a temple complex around 50 kilometres west of Alexandria. For years, an international team has pursued a bold possibility there: that Taposiris Magna may be where Cleopatra VII and her lover Mark Antony were buried.

A newly discovered harbour off the coast places Taposiris Magna at the centre of today’s most spectacular search for a tomb.

The leading advocate of this theory is Dominican researcher Kathleen Martinez, formerly a criminal defence lawyer and now an archaeologist with longstanding links to National Geographic. She views the harbour discovery as another piece in a wider picture formed by inscriptions, religious architecture, pottery and coins.

Why Taposiris Magna could be Cleopatra’s final resting place

Cleopatra is regarded as the best-known ruler of Ptolemaic Egypt. She ruled from 51 to 30 BC, presented herself as a reincarnation of the goddess Isis, and cultivated the image of a divine queen in both domestic and foreign affairs. Following her defeat by Octavian at the naval Battle of Actium, she took her own life, probably in Alexandria. No confirmed trace of her tomb has been found since.

The Roman victor had a clear intention: he wanted to display Cleopatra in Rome as a trophy of his power. The fact that this never happened turned her into a legend even in antiquity. Later accounts refer to a burial, but remain vague about both its location and form. Alexandria was long considered the most likely candidate. Part of the ancient city now lies underwater, having sunk into the sea as a result of earthquakes and ground subsidence.

Martinez deliberately began from a different perspective. She asked which site would have made theological, political and military sense in the final years of the Ptolemaic kingdom. Her answer was Taposiris Magna, a temple complex devoted to Osiris and Isis – precisely the deities with whom Cleopatra identified herself.

Evidence pointing to Taposiris Magna

• Religious significance: The temple was an important centre of worship for Osiris and Isis, who played a central part in Cleopatra’s self-presentation.
• Archaeological finds: Coins bearing her portrait, along with pottery and votive offerings from her reign, have been uncovered.
• Tomb structures: Researchers have exposed several burial chambers within and beneath the temple, thought to have been intended for high-ranking individuals.
• Military position: At the time of Cleopatra’s death, Taposiris Magna apparently remained outside Roman control – a strategic advantage.

This particular combination has led Martinez to believe that Cleopatra may have chosen burial at a place rich in symbolism while still offering a reasonable degree of military security. The newly reported harbour fits strikingly well into that theory: it may have provided access for processions, priests and valuable funerary goods travelling to the temple.

How a sunken harbour could transform the Cleopatra tomb search

For now, the newly identified harbour consists mainly of wall sections, mooring structures and scattered building remains. Satellite imagery, dives and underwater scanning techniques such as sonar suggest that the complex was considerably larger than initially thought.

For the search for Cleopatra’s tomb, this means that the setting around Taposiris Magna must be reconsidered. If the temple had its own harbour, it was apparently more closely connected to Mediterranean trade than previously assumed. That makes it more likely that the complex carried greater political and religious importance than older textbooks suggested.

The more significant Taposiris Magna was, the more plausible it becomes that Cleopatra chose to establish a tomb there with the greatest possible symbolic force.

Martinez and her team intend to intensify their underwater work in the coming months. Planned work includes systematic dives, sediment sampling, underwater photogrammetry and 3D reconstructions. The aim is to establish whether the harbour was directly connected to the temple’s religious areas, or even contained separate ritual zones that remain unknown.

Documentary follows the demanding mission

National Geographic is documenting the work on film. The documentary Cleopatra’s Final Secret is intended to show the combination of traditional fieldwork, advanced technology and personal obsession involved. It is already clear that the hunt for Cleopatra is less a romantic treasure quest than a painstaking struggle with evidence, hypotheses and measurement data.

The film also highlights the risks involved. Underwater work is dangerous, and access to certain areas is severely restricted. Currents, poor visibility and the potential danger of collapses within ruins make every minute underwater more difficult.

What the discovery of Cleopatra’s tomb would mean

If the Taposiris Magna theory proves correct, archaeology would be facing a discovery of the century. Cleopatra’s tomb would rival that of Tutankhamun in importance, perhaps even surpass it. Whereas Tutankhamun became an icon largely by chance, Cleopatra represents an entire era between the pharaonic kingdom and the rise of Roman world power.

An undisturbed tomb – if one still exists at all – could answer questions that have occupied researchers for decades:

• How did Cleopatra really die, beyond the literary accounts?
• What part did Roman envoys play during her final days?
• What did funerary worship look like at the end of the Ptolemaic dynasty?
• Which political messages were conveyed by the tomb’s furnishings?

Egypt would also face a delicate balancing act. Such a discovery would attract millions of visitors from around the world. Pressure to open the site to the public would be immense, while conservation concerns would favour a more cautious approach. The country has already spent years trying to reduce visitor pressure at celebrated locations including Luxor, the Valley of the Kings and Abu Simbel.

How underwater archaeology works in Egypt

The announcement of the sunken harbour joins a long series of maritime discoveries. Over recent decades, teams off Alexandria have located parts of the ancient lighthouse, statues, columns and entire harbour installations. The once-submerged cities of Heracleion and Canopus likewise demonstrate how extensively the coastal zone has subsided over time.

A typical investigation generally follows these stages:

• Preliminary research using historic maps, written sources and geological data.
• Survey runs with sonar and magnetometers to identify structures beneath the ground.
• Targeted dives at notable locations, supported by photographic documentation.
• Collection of samples, followed by dating and material analysis on land.
• Gradual excavation of the most relevant areas.

Every one of these stages requires time, funding and permits. Politics is also a major factor in Egypt: archaeology is part of the country’s image-making. Discoveries generate headlines, while new museums and prestige projects are intended to reinforce Egypt’s standing as the cradle of civilisation.

Why myths surrounding Cleopatra endure

Cleopatra captivates not only historians, but also popular culture, literature and cinema. One reason is that she stands at a historical turning point. Her death brought Ptolemaic rule to an end, and Egypt became a province of the Roman Empire. At the same time, a wave of propaganda about her was unleashed. Roman writers preferred to portray her as a seductive schemer – an image that persists to this day.

Modern scholarship is attempting to correct that stereotype. The evidence points towards a politically well-educated, multilingual ruler who skilfully navigated between Hellenistic and Egyptian traditions. A tomb containing original inscriptions, statues and symbols could considerably sharpen or revise that picture.

There is another element, too: terms such as “female pharaoh”, “divine queen” and “ruler of the Nile and sea” have an immediate effect on many people. They evoke epic cinema, shadowy palaces, golden treasures and dramatic love stories. It is precisely this mix of archaeology and emotion that makes the search for her tomb so compelling.

Why this case matters to German-speaking readers

For German-speaking audiences, the question is often: apart from being fascinating, what does this have to do with us? More than may be apparent at first glance. German and Austrian institutes have been active in Egypt for decades, including in the Valley of the Kings, at Saqqara and at Nubian temple sites. Many modern analytical methods – from 3D scans to ancient DNA analysis – were also developed with the involvement of European laboratories.

If Cleopatra’s tomb is genuinely found, cooperation with research institutions in German-speaking countries would be highly likely. Radiological analysis, materials research and conservation all require international collaboration. For museums in Berlin, Munich, Vienna and Basel, such a discovery would be a major draw for large special exhibitions.

Until then, the matter remains a wager on the future. Kathleen Martinez confidently says that it is “only a matter of time” before the veil is lifted. The sunken harbour off Taposiris Magna at least strengthens the impression that the search is emerging from a dead end and entering a phase in which every new excavation season could provide real answers – or raise entirely new questions.
