The desert north of Arabia has kept a Roman military story out of sight for almost two thousand years. Now three angular traces in the landscape are giving archaeologists a possible route to follow. Researchers working with satellite imagery have identified three Roman marching camps in the Harrat al-Shaam region, close to the ancient frontier […]
Researchers from the University of Catania, in collaboration with the Archaeological Park of Catania and the Valley of the Aci, have located beneath the stage of the Teatro Antico a network of underground channels that in Roman times was used to intercept and evacuate groundwater toward the sea. The discovery, the result of a geoarchaeological […]
The history of the Roman Empire is often told through the exploits of emperors and generals, but the mechanisms of daily administration and, especially, the relationships between central power and the provinces, constitute an equally revealing field of study to understand the dynamics of that civilization. In this context, the discovery and subsequent analysis of […]
Excavations carried out as part of the National Recovery and Resilience Plan (PNRR) have brought to light an architectural complex of incalculable value in the heart of Villa Celimontana. Under the supervision of the Special Superintendency of Rome of the Ministry of Culture, the work has uncovered eight rooms belonging to an Imperial-era building whose […]
The Turkish Minister of Culture and Tourism, Mehmet Nuri Ersoy, has announced the completion of the excavation and restoration works of an ancient pool located in the frigidarium of the monumental complex known as the Hamam Gymnasium, within the ancient city of Tralleis, in the province of Aydın. The newly restored structure has remarkable dimensions: […]
In the summer of 15 BC, Emperor Augustus’ two stepsons, Tiberius and Drusus, brought the Central Alps and the Swiss Plateau under Roman control. That campaign concluded decades of efforts to link the Gallic provinces with Illyricum and secure the routes between northern Italy and the Danube. However, while the western and eastern routes of […]
The construction of the new variant of the A8 highway in the area known as the Albaufstieg, south of Stuttgart (Germany), has uncovered a first-rate archaeological find: a segment of the ancient Roman road that, two millennia ago, structured defense and trade along the Empire’s frontier. The discovery reveals a stretch of approximately ninety meters […]
The educational excavation campaign that the University of Vienna has been conducting since mid-July in the municipality of Hannersdorf, in the Oberwart district southeast of Vienna, has brought to light the remains of two pottery kilns from the Roman era in the first fifteen days of work. The work, led by archaeologist Basema Hamarneh, focuses […]
A team from the University of Granada has confirmed that a room in the Roman villa of Fuente Álamo, in the municipality of Puente Genil, functioned as a library, making it the oldest documented in the Iberian Peninsula and one of the best-preserved in the entire Empire. The study, published in the Journal of Mediterranean […]
The archaeological campaign carried out during May and June 2026 in Cova Dones, located in the Valencian municipality of Millares in southeastern Spain, has completely transformed the previously known scope of this underground site. The work, led by researchers from the Universities of Alicante and Zaragoza, has documented a total of 120 Latin inscriptions on […]
The emergency archaeological intervention promoted by Cantonal Archaeology on Zürcherstrasse Street in Windisch (in the Swiss canton of Aargau) has concluded within the expected timeframe, according to sources from the institution in mid-July. The excavation team, composed of around twenty specialists, worked for eleven months on an area of approximately 4,000 square meters—the future site […]
The presentation of the project took place in the Palestra Grande of the Excavations, at the end of the International Workshop Pompeii: Excavations and Ongoing Research, held in the Park Auditorium. During the meeting, representatives from Italian and foreign institutions and universities participating in research activities at the site shared the progress of their respective […]
The Roman soldiers who guarded the Danube frontier almost two thousand years ago did not live on bread and vegetables alone. The analysis of more than 10,000 animal bones found at the Diana-Karataš fort, in eastern Serbia, demonstrates that meat was a regular part of their diet and that it varied significantly over the six […]
Now scholars may finally be closer to knowing the answer, according to new findings published in the Journal of Ancient History and Archaeology. The research presents evidence drawn from several case studies that help to build the argument that many ancient Roman coin hoards were buried during periods of political upheaval, war, or other catastrophic periods of change, revealing that the recovery of these caches may not have always been practical, or even possible.
The Enigma of Roman Coin Hoards
For many centuries, treasure hunters, archaeologists, and others have made remarkable discoveries of buried hoards of Roman coins across Europe, North Africa, and the Middle East. Although the reasons why coin hoards were buried are sometimes fairly obvious, the real mystery for scholars throughout time has to do with why these troves—often representing significant amounts of wealth—remained unrecovered.

To answer this question, Babeş-Bolyai University researchers Adrian-Daniel Stan and Cristian Gǎzda leveraged one of the world’s largest databases on Roman coin hoards, and based on the data the pair reviewed, they suggest that these “forgotten fortunes” entombed within the earth can be viewed as the fingerprints left behind by some of the darkest periods in the Roman Empire.
A Deeper Look at Roman Coin Hoards
Managed by the Ashmolean Museum and the University of Oxford, the Coin Hoards of the Roman Empire (CHRE) project is an extensive database comprised of more than 18,000 documented hoards.
With data on more than 7.5 million coins, the project’s database provided Gǎzda and Stan precisely the kind of information they needed to contrast discoveries of large troves of wealth buried throughout the ancient Roman world.
However, rather than focusing their study on why Romans hid their valuables in the first place, which has long remained the focus in past archaeological research, the team decided to try to better understand what prevented their reclamation.
Coin hoards were buried for a variety of reasons. Sometimes merchants would hide their wealth to conceal it from thieves or tax collectors. In other instances, treasure caches might have been buried for religious reasons, such as offerings or as part of rituals.

In at least some instances, circumstantial clues help to illustrate that the hoards had been buried in what were intended as temporary hiding places, sometimes contained within ceramic vessels, bags or pouches made from leather, or within other kinds of containers.
Such discoveries have often been located below the flooring in houses or hearths—locations where it was likely expected that they would have been retrieved by their owners. When these hoards remained buried, it likely means something went wrong.
Aligning with this “catastrophic” interpretation, Gǎzda and Stan relied on spatial and chronological analyses of the CHRE database, which revealed clusters of unrecovered hoard discoveries that frequently coincided with major upheavals that included wars, invasions, and natural disasters known in the historic record.
The Battle of the Teutoburg Forest
One example the research team focused on occurred in A.D. 9, where a trio of Roman legions was obliterated by Germanic tribes. This event, known as the Battle of the Teutoburg Forest, aligned with several coin hoards found around a battlefield area at Kalkriese, as well as the nearby Roman fort of Haltern; a pattern implying that soldiers and civilians had likely buried their valuables, and never had opportunities to recover them.

Similar patterns were observed in Britain, where concentrations of hoards matched with periods of tribal warfare, as well as the beginning of the Roman conquest in A.D. 43, and other instances. Further south, another concentration appears around Mount Vesuvius just after the devastating eruption that occurred in A.D. 79, which buried Pompeii beneath a blanket of volcanic ash.
Still other examples of hoard “clusters” emerge from the data in areas that include the Danube frontier during the Dacian Wars, and amid invasions that were prevalent during the crisis period the Roman Empire underwent during the third century.
Overall, the patterns reveal that these unrecovered hoards provide a unique archaeological record of upheaval and insecurity in the ancient world that helps to complement and verify written history and other archaeological research.
A Tale of Two Phenomena
Significantly, Gǎzda and Stan observe that there are two distinctive phenomena that emerge from these failures to recover buried treasure. One involved the practical concern of protecting one’s wealth, and avoidance of taxation, while the other involved more tragic circumstances like death, displacement due to battle, invasion, natural disaster, or other dramatic periods of change.
Through this lens of understanding, the buried coin hoards become more than just intriguing discoveries of lost valuables from ancient times: they offer a unique record of some of history’s most unpredictable forces, and a deeper perspective on the ways humans coped with insecurity while trying to survive and cope with changes in the ancient world.
