There is a 35 acre platform in the heart of Jerusalem where the conventional tools of archaeology are essentially forbidden.
You cannot dig, you cannot drill, you cannot sink a bore into the ground to take a soil sample.
Three major world religions consider this ground sacred.
And the political consequences of mishandling any work here are not hypothetical.
They are documented and recent.
And yet beneath this platform, beneath the stone that pious feet have worn smooth over 3,000 years, something is down there that we have not fully accounted for.
The sistns, the tunnels, the foundation walls, the sealed chambers and buried store rooms of every civilization that has built and rebuilt on this hill since at least the 10th century BCE.
All of it sitting in the dark, unexavated, and until very recently, essentially impossible to study without touching the ground that cannot be touched.
That changed with a decision made by two professors at Tel Aviv University, a physicist and an archaeologist, who in 2023 repelled into an underground cavern beneath Jerusalem’s old city carrying equipment the size of a household dresser and asked a question that no one had managed to ask before with anything resembling scientific rigor.
What is actually under there?
The answer they are now extracting from that question using subatomic particles that rain continuously from deep space and an artificial intelligence system trained to read the patterns in those particles is already rewriting what we thought we knew about the underground architecture of ancient Jerusalem.
And the most extraordinary result of their work so far, an unexpected finding that the AI returned from its very first deployment was not what anyone on the team was looking for.
My name is Elias and I want to take you through this carefully because what is happening beneath the Temple Mount right now involves real scientists, real institutions, real peer-reviewed methodology and real results that deserve exactly the kind of attention the sensational framing usually prevents them from getting.
Start with the site and the problem because you need to understand both to appreciate why this approach is as significant as it is.
Research into the subject of Jerusalem in general and the temple in particular is almost at a standstill due to today’s political and religious constraints.
It is impossible to dig in and under the temple mount.
That is not a journalistic observation.
That is how the researchers themselves describe the situation.
The temple mount known in Arabic as Haram al- Sharif, the noble sanctuary is administered by the Jordanian Islamic Wak and is among the most politically charged locations on earth.
Three of the world’s major monotheistic religions center significant portions of their historical and theological identity on this specific piece of ground.
For Jews, it is the holiest site in existence.
The location of both the first temple built by Solomon around 960 B.CE and the second temple destroyed by Rome in 70 CE.
For Muslims, it is Islam’s third holiest site, home to the Alexa mosque and the Dome of the Rock.
For Christians, it is where Jesus taught and where pivotal events described in the New Testament occurred.
Any archaeological work on the surface requires approvals from multiple religious authorities, government agencies, and international bodies.
Those approvals do not arrive easily or often, and direct excavation of the platform itself has not been conducted by professional archaeologists under documented conditions in modern times.
It becomes more important to make use of non-penetrating geoysical methods whenever possible to gather information about the subterranean features of the compound.
These methods include ground penetrating radar investigations through the outer walls of the mount, high frequency seismic tests through the walls, magnetic mapping, and thermal infrared imagery.
All of those methods have been applied to various degrees over the past several decades.
None of them has produced a complete highresolution map of what the underground environment actually looks like.
The constraints of the site limit where equipment can be placed, how long it can operate, and how the data can be interpreted without ground truth verification from physical excavation.
What the Tel Aviv University team developed changes the fundamental geometry of the problem.
Instead of trying to scan from above, they went below.
The technology is called muon tomography and it works on a principle that is elegant in its simplicity and extraordinary in what it can accomplish.
Muons are particles carrying an electrical charge similar to electrons or protons.
They are primarily created by the interaction of cosmic rays with the Earth’s atmosphere.
They rain down from the atmosphere continuously at a rate that is constant and well understood.
They travel at nearly the speed of light and they pass through almost everything.
Solid rock slows them slightly and absorbs a predictable fraction.
But where there is empty space, a void, a tunnel, a sealed chamber, the moons pass through with almost no resistance.
If detectors placed below the surface receive more muons than expected, it means that for at least part of their underground journey, the particles didn’t travel through matter, but through an empty cavity.
The detector is placed below the thing you want to study.
Muans fall from above.
If the count coming through a particular angle is higher than the count you would expect from solid rock of the known density, something hollow sits along that path.
If it matches exactly solid stone, if it is anomalous, something else, the technique is not new.
Nobel physicist Luis Alvarez’s team used muon detectors to scan inside the pyramid of carfrey in Egypt in the 1960s.
And in 2023, researchers discovered an unknown chamber in the Great Pyramid in Giza using the same method.
That corridor, a space more than 30 ft long, hidden inside the most studied monument on Earth, had remained undetected for more than four millennia until Muan tomography found it from outside the structure without a single stone being moved.
The AI component is what processes the raw muon count data into something interpretable.
Professor Ereszion of Tel Aviv University’s School of Physics and Astronomy said the project set out to develop a simple lowcost method to produce a 3D map of what lies beneath the bedrock using artificial intelligence as well so that archaeologists can arrive at a site already knowing the underground layout and decide where to dig accordingly.
The AI takes the angular distribution of Muan arrivals recorded by the detector and processes it into a three-dimensional density map of whatever sits above.
Denser material produces fewer counts.
Void space produces more.
The AI learns the expected baseline for a given site and flags deviations as potential features, distinguishing empty chambers from solid rock with a precision that no previous non-invasive technique has matched.
The deployment that produced the first verified results happened in 2023 under considerably more difficult conditions than a standard laboratory experiment.
To get the detectors into place, the research team had to repel into a cavern using ropes and pulley to bring in the scientific equipment.
It was an extremely challenging task, Etsen said.
In the lab, we are in a sterile environment.
Here we rebuilt a detector in a few crazy days under the ground where it’s dark and humid, far away from a clean laboratory with ideal conditions.
The installation sites were in the city of David, the area immediately south of the temple mount that represents the oldest continuously inhabited portion of Jerusalem.
One of the large muan detection devices was positioned near the Guihon spring, while a second device was installed at the stone stepped structure, a large wall in the city of David dating back approximately 3,000 years.
The Guihon spring is the ancient water source that made Jerusalem viable as a city.
Without it, there is no city.
Every major defensive and hydraulic engineering project of ancient Jerusalem was connected to protecting and channeling access to this spring.
Hzakia’s tunnel, the Warren Shaft system, the Salom channel, a network of water infrastructure built and modified over more than a thousand years of continuous occupation.
What that means for the Muan project is that the underground around the Guhon Spring is already known to be complex, layered, and full of voids.
The question is whether voids that are not yet known, tunnels and chambers that have not been entered in modern times, can be detected passively without disturbing anything.
Subscribe now because the first results from those detectors, published in peer-reviewed form and carrying the weight of Tel Aviv University’s physics department behind them, returned something that reshaped what the team thought it was going to find and set the stage for the larger question that Erisets has stated publicly as the project’s ultimate ambition.
The results from the initial deployment confirmed what the technique could do, and they hinted at the complexity of what lies beneath the surface in ways that previous surveys had not fully captured.
The density maps generated by the AI processing showed multiple subsurface features in areas adjacent to known tunnels, features consistent with voids or cavities that extended beyond the previously documented tunnel network.
The team was careful not to overclaim.
The resolution of Muan tomography is determined by the exposure time, the size of the detector, and the depth of the target.
Longer exposures and larger detectors produce better resolution.
And the 2023 deployment was explicitly described as a pilot, a proof of concept demonstrating that the technique could function in the specific challenging conditions of Jerusalem’s underground environment.
One of the team’s key goals, Lipkit said, is to create portable, affordable Muan detectors and software so that excavations anywhere in the world can employ the technology.
But the pilot did something beyond validating the methodology.
It demonstrated that the underground environment of ancient Jerusalem is more extensive and more architecturally complex than the currently documented tunnels suggest.
The Muan counts coming through certain angles did not match what solid rock would produce.
Something is there that has not yet been mapped and the direction of the team’s stated ambition is explicit.
It is our dream to scan underground in a search for tunnels that might lead us to the temple mount.
Etsian said, “The Muan detectors can provide us with tools to search underground passively, passively, without digging, without disturbing a single stone of the most contested ground on Earth.
The tool that could finally answer the question of what lies directly beneath the Temple Mount platform exists and is operational.
Whether it will be positioned to look in that specific direction depends on political and logistical conditions that are beyond the physics department’s control.
That is where the Muon project currently stands, not a complete answer.
A door that has been built and is waiting to be opened.
While the Muan project pursues the underground from below, a parallel effort has been producing documented results from a completely different direction.
And its most recent discovery announced in July 2025 carries implications that stopped archaeologists who study this period in their tracks.
In November 1999, the Islamic WAF carried out a construction project in and around the newly built Elmarwani mosque beneath the Temple Mount platform.
Approximately 9,000 tons of archaeologically rich soil were removed from the temple mount using heavy earthmoving equipment and without a preceding salvage excavation or proper archaeological care.
The debris was moved to several locations with an estimated 350 truckloads dumped in the Kidron Valley.
The material that was removed was not inert fill.
It was the accumulated soil of 3,000 years of human occupation on one of the most historically significant locations on Earth.
Fragments of pottery, coins, architectural elements, organic material, personal objects, and administrative artifacts from every period of the site’s documented history.
From the first temple era to the present, it was disposed of as construction waste.
Israeli archaeologists watching the operation understood immediately that a unique archaeological record was being destroyed.
What emerged from that crisis was the Temple Mount sifting project, an initiative that collected the dumped soil and transported it to Emiksurim National Park, where volunteers and researchers have been systematically sifting through every cubic cm using water flotation, fine mesh screens, and magnifying equipment, looking for material of historical significance.
To decipher artifacts, the researchers now use special reflectance transformation imaging or RTI photography.
This technique creates a composite image by photographing an object multiple times from the same spot under changing light conditions as the source of light moves around the object at the same distance.
The composite image reveals surface details that no single photograph under any fixed lighting condition could show, including inscription strokes so faint that they are invisible to the naked eye, even under magnification.
This is the AI assisted imaging at the heart of the most significant recent discovery from the project.
In July 2025, archaeologist Morai Erlick was examining a container of material recovered by the sifting project when he noticed something that looked at first like a piece of bone.
The artifact had the color of bone, but Erlick realized it was a clay object and there was an inscription on it.
What he was holding was a buller, a clay seal impression used in the ancient near east to authenticate and secure documents and storage containers.
Boule were made by pressing a carved stone seal into a small lump of soft clay that was then attached to the cord or covering of a sealed item.
The clay hardened and preserved the impression functioning as both an authentication mark and a tamper evidence seal.
Researchers Dr.
Anat Mendul Gabberovich and Zaki Deira read the inscription as belonging to Yedaya, son of Asayyahu and dated the script style to the late first temple period, approximately the late 7th to early 6th century B.C.E.
The buller was deciphered using the RTI photography system and the AI processing that reconstructs surface topography from the lighting composite.
The inscription is in PaleoHebrew, the [clears throat] ancient script form used in Judah before and during the Babylonian period.
And this is only the second time since the Temple Mount sifting project began over 20 years ago that an inscribed ceiling with such a complete inscription has been uncovered with nearly every letter clearly legible.
Subscribe now because what the name on that seal connects to in the biblical record is the part that researchers described as immediately striking when they completed the decipherment.
The name Asayahu, the father of the seal’s owner, appears in the Bible in a specific and datable context.
The Bible mentions a figure in the Jerusalem administration bearing the very same name during the reign of King Josiah.
Anglicized asiah the king’s servant.
Josiah ruled Judah from approximately 640 to 609 B.CE.
His reign is one of the most documented in the biblical record.
It included a major religious reform, the rediscovery of the book of the law during temple renovations, and a confrontation with Egypt at Megiddo in which Josiah was killed.
The date range assigned to this buller by its physical characteristics and its script form places it squarely in Josiah’s era, the late 7th to early 6th century B.CE.
The Temple Mount sifting project’s researchers consider the possibility that the ceiling belongs to the son of King Josiah’s trusted official as highly plausible.
What makes this finding significant beyond the name connection is what the buller physically represents.
The reverse of the clay buller bore cord marks consistent with its use sealing a bag or container, and the object still displayed a partial fingerprint that specialists interpreted as the impression of its ancient handler.
A partial fingerprint from approximately 2,600 years ago.
The person who pressed this seal into clay and attached it to a storage bag in the temple administration left a biological trace that survived the Babylonian destruction of 586 B.CE.
Survived centuries underground.
Survived being bulldozed and dumped as construction waste in 1999.
And survived decades of sifting before Morai Erlic noticed it and recognized it for what it was.
That fingerprint is the closest physical connection any researcher has yet established between a named individual in the biblical record and a material object recovered from the temple mount itself.
The buller does more than connect a name to a period.
It is physical evidence of an administrative system that the biblical texts describe in considerable detail.
But that archaeology had until this project largely been unable to verify from the temple mount itself.
A study conducted on dozens of clay ceilings recovered in sifting of temple mount soil has successfully identified evidence of both the temple treasury and the royal treasury of the kingdom of Judah.
The analysis demonstrates that their primary function was the administration of goods kept in store rooms, a fact particularly evidenced by the large percentage of ceilings which bear the impression of woven fabrics on their reverse.
About 21% of the first temple period ceilings found in the sifting of soil from the temple mount carried impressions of woven fabrics on their reverse.
Ceilings that were concave and had fabric impressions were apparently attached to a bag made of coarse fibers which likely contained pieces of silver.
While ceilings with flat reverses and fabric impressions probably sealed containers whose openings were covered with woven cloth and in which agricultural produce was stored.
The temple was not only a religious building.
It was an administrative center, a treasury, a grain storage facility, a bureaucratic hub that managed the economic life of a significant ancient state.
The clay seals are the administrative paper trail of that operation.
Every one of them represents a transaction, a sealed delivery, a storage authorization, a moment of commerce or worship that someone in the system signed off on with their personal seal.
And those paper trails, those administrative artifacts that a functioning bureaucracy generates in the thousands are coming out of the soil of the Temple Mount in ways that allow researchers to reconstruct the operational structure of an institution that was destroyed 2,600 years ago.
The AI enhanced imaging that makes the inscriptions legible is the bridge between an artifact that looks like a fragment of bone and a direct connection to a named official in the court of King Josiah of Judah.
Now set both of those developments alongside the ground penetrating radar surveys that have been conducted on and around the Temple Mount over recent years.
And the picture that emerges is of a site whose subsurface is far more complex and far more intact than the conventional assumption of millennia of construction and destruction would suggest.
A research team working beneath the ancient strata of Jerusalem has reported structural anomalies consistent with a sealed chamber dating to the late first temple or early second temple period.
The announcement which came in early 2026 was careful in its framing.
The claim is not that a specific artifact has been found in a specific location.
The claim is that the subsurface imaging data contains a signature inconsistent with solid rock and consistent with an enclosed void of significant dimensions at a depth and location that places it within the period when the first temple was standing.
Ground penetrating radar scans, electromagnetic mapping data, subsurface imaging models, and renewed archival research are converging with speculation accelerating across academic, religious, and media circles about what a sealed first temple or early second temple chamber might contain.
The most discussed possibility among those who study this site seriously rather than those who approach it through the lens of treasure hunting is not a dramatic physical object.
It is documentation.
The administrative records of the temple, the sealed scrolls and inscribed tablets that a functioning ancient Neareastern institution would have maintained.
Stored in a sealed chamber under conditions that have preserved them from the destruction of 586 BCA and from everything that followed.
Whether that possibility is live depends on whether the anomaly is real, whether it is what it appears to be, and whether any technology will ever be permitted to resolve the question in the way that physical excavation would.
That last condition is the one that has no current answer.
Here is what the convergence of these three research streams actually tells us.
Stated as carefully as the evidence permits.
The Muantom tomography project has demonstrated for the first time in a peer-reviewed and reproducible form that the underground environment of ancient Jerusalem extends beyond the currently documented tunnel network in ways that passive scanning can detect.
The AI processing of the Muan data produces three-dimensional subsurface maps that identify features not visible from the surface and not previously cataloged.
The tool to answer the question of what lies directly beneath the Temple Mount platform now exists and has been validated in field conditions adjacent to the site.
The Temple Mount sifting project has demonstrated through more than two decades of systematic work and more than 4.5 tons of recovered artifacts that the administrative and material culture of the first temple period is physically present in the soil removed from the platform.
The July 2025 buller deciphered through AI enhanced RTI imaging and bearing a fingerprint from 20600 years ago is the most direct connection yet established between a named biblical era individual and material recovered from the temple mount.
The ground penetrating radar surveys conducted through the outer walls of the platform have identified subsurface anomalies that researchers describe as consistent with sealed voids at depths and locations corresponding to the first and second temple periods.
The question those anomalies raise cannot currently be answered without access to the surface above them.
What all three of these research directions share is that they were made possible by non-invasive technology.
They did not require a shovel.
They did not disturb a single stone of the most contested ground on Earth.
They used cosmic rays falling from deep space, AI processing of subatomic particle data, and light manipulation photography to extract information from a site that has been functionally sealed to archaeology for decades.
The unexpected finding that gave this investigation its sharpest focus was not a dramatic hidden chamber or a named treasure.
It was the fingerprint, a partial fingerprint on a clay seal recovered from construction waste.
From a buller that looked like a bone fragment, from soil that was dumped illegally 26 years ago.
From a bureaucratic record created in the administration of a king who died 205 years ago fighting the Egyptian army at Megiddo.
Every step of that chain of survival is a small miracle of preservation and recognition.
The fingerprint survived because the clay was fired by the heat of the same Babylonian destruction that ended the first temple period.
The buller survived because it was small and dense and unremarkable.
The inscription survived because someone noticed it was not a bone.
The AI imaging system made the letters legible.
The epigrapher read the name.
The connection to the biblical record was there waiting in the text and the physical object and the written account bound each other across a gap of 2 and 1/2 millennia.
That is what the convergence of technology and scholarship is doing at the Temple Mount.
Not unlocking a vault in a single dramatic moment.
Recovering piece by piece the fingerprints of the people who built and administered and woripped and worked inside one of the most important structures in human religious history.
Recovering them from soil that was treated as refues using tools that did not exist a decade ago and building from those recoveries a picture of a place that still holds in its sealed underground depths.
The physical record of everything that happened there before the fires of 586 BCA made the surface indistinguishable from ash.
The Muan detectors are running beneath Jerusalem right now.
The sifting continues at Emtt Zurim.
The imaging systems are processing each new artifact.
And somewhere beneath the platform that cannot be touched, the subsurface anomalies that the radar has identified sit in the dark, exactly where they have been for 26 centuries, waiting for a technology and a political moment to arrive at the same time.
Because the moment when those two things converge is the moment this story changes permanently and by the evidence it is closer than it has ever been.
