Some historians think for a few hundred years Hadrian's Wall was a megastructure where the locals had no solid understanding of who built it, how they managed it, or why.
It's admittedly debated, but even if just plausible, still fascinating to contemplate.
If not for the wall, there were probably periods in the local history around the pyramids that would qualify. Julius Caesar is closer to our time than he was to the time when they were built. There's a lot of time for people to forget other civilizations in there.
> It was so well-known that it allegedly factored into the plans of military legends such as Genghis Khan. Today, however, it’s been almost entirely forgotten—many locals living within a few miles of it don’t even know of its existence.
That sounds plausible. I have heard a similar story about the ruins of the Roman baths at Bath, Somerset in medieval times: the locals thought that they were built by vanished giants.
This is still true of Stonehenge, Avebury, and some of the less well-known archaeological remnants in that area. (Durrington Walls, Marden Henge, and so on.)
I think with Stonehenge and the like, the thing some people find mysterious is how they were built using the technology of the day. (I don't find it mysterious, I think they did things by working hard and being clever).
The claim about Hardian's wall is that after the fall of the Roman Empire, the medieval people didn't know how to build such things at all, and could only guess how the Romans had done it. And part of those guesses might well have been "by magic".
Completely implausible, we're talking about medieval Europeans, not Flintstones era simpletons. The concepts of fortification and putting one rock on top of another were pretty well hashed out by then.
I assume they're not unknown to science as they're pretty prominent, but then again they're not marked on the Ordnance Survey map as such things tend to be, like the Roman Camps just to their north west for example (http://streetmap.co.uk/grid/375689_566022_120).
Whatever they are they are fairly visible in Bing Aerial view (NB I used Bing as they have OS 1:25,000 maps).
Edit: Speaking of things not being on OS maps - I've noticed that over the last ~40 years (since I started looking at OS maps at an early age) that they show far less historical details than they used to. I don't know if this is policy to keep maps less cluttered or because many things in agricultural areas simply have been ploughed over so many times that nothing remains. A shame either way.
They do appear as "Roman camp" on an OS at the right scale - try the website, where you can sign up for free for a week. Or the Heritage Gateway website mentioned by ascorbic.
There's a lot in the area that's still to be dug. It's a matter of finding the money to fund digs.
I get the idea of grabbing the things most important to you before you and leaving your stuff behind in favor of kids (I guess), but what I'm curious about is what caused them to cover the barracks in the first place.
I mean if you have got the time to cement over barracks for 1000 people surely you have time to pack up!
According to the article, the concrete floor was laid about 30 years after the artifacts were abandoned. If I understand it right, the fort had been raised and leveled more than once in between, so there was a thick layer of soil and debris between the floor and the artifacts at the time the floor was laid. The unknown question is why such valuable items were left the first time the fort was abandoned.
I suspect the artefacts weren't in a brick-and-tile building but a wood-and-thatch outbuilding, which after 30 years of abandonment would have collapsed and rotted over the contents.
> As well as other weapons, including cavalry lances, arrowheads and ballista bolts – all left behind on the floors – there are combs, bath clogs, shoes, stylus pens, hairpins and brooches.
Reading about these digs I've always been curious that given the large number of artifacts found if it is a common phenomenon for the people involved in the dig to 'steal' or bring home certain items for themselves that we'd never find out about? Clearly these are people most interested in the subject at hand so I could see a motivation...
I'd imagine that most of the wall has been metal detected by hobbyists throughout the years. I don't know how much of it is under protection but from various videos on YouTube it seems like a great section of it goes thru farmlands out in the boonies. A pretty easy target to hit with a metal detector without anyone noticing.
Was the site under threat of looting or construction, or was this a massive stewardship failure?
For context, once upon a time, archaeologists "carefully" used dynamite, and excavated entire sites. Leaving nothing at all behind, but for a few "carefully" washed and polished artifacts (the "important" trophies, like weapons and jewelry), and perhaps some "carefully" hand-drawn sketches of some big things (formerly) at the site.
Nowadays, archaeologists "carefully" crack open an anaerobic site, ... and I just don't have the heart to finish this post.
Does anyone have a good link on archaeological ethics, and limiting excavation to only threatened sites? The idea is to avoid unnecessary excavation, because it destroys vastly more information than it preserves. Information which could have been captured with improving technology, if only the excavation had happened later.
This article is ghastly, close to parody. Picture of volunteer displaying "the icing on the cake" trophy in ambient atmosphere, sitting on newspaper, the 'who cares about dirt?' brushed off, at best coarsely sieved, then discarded on a big pile. The Birley quotes... show no recognition that anything unfortunate has happened.
I suggest you discuss this directly with archaeological faculty at a university, rather than making claims about dynamite - e.g. those who used dynamite were treasure hunters, for example, not archaeologists. Modern archaeologists do share your distress over most of what you've claimed.
For instance, you say "Information which could have been captured with improving technology, if only the excavation had happened later." A not-insignificant amount of archaeology is performed because of an imminent threat to a site, be it natural (rising oceans) or man-made (highways). I recall reading about (what I consider to be) significant Roman sites in London being destroyed after examination because a developer had a building plan for that particular location.
Even Time Team would dig up mosaics in a field, record everything meticulously, present their findings to the public (in a rather unscientific manner), and then bury it again, to protect it.
Go and expand your horizons, instead of making decisions based upon incomplete information. You have some pleasant surprises waiting for you.

My experience with academic archaeologists has been that they are pretty myopic on this. They like to dismiss past archaeologists as treasure hunters, but they are also eager to get their hands on all the data they can without much regard for the locals or for preservation. They usually justify this by pointing out that they aren't looking for treasure, in the traditional sense.

I wonder if anyone has done a survey of views? There is some "do no harm", exploit non-destructive techniques, and reserve excavation for rescue archaeology. But seemingly a variety of other standards of care for site conservation and consumption.
Not my field, but one thing I've anecdotally seen underappreciated, is the rate of change in molecular biology, and thus eventually in molecular archaeology (aka bioarchaeology outside the US). Where over a mere decade or two, "can't imagine doing X" can change to "doing X costs years and millions", and then to "new trainee can casually do X in an afternoon", and even to "X is a field-deployable box". With a potential impact... for example, it turns out tooth calculus preserves DNA. So from millennia old teeth, one might sequence the owner, their mouth microbiome (with health information), and the species they've been eating. Grabbing a few soil samples might be ok if you're thinking pollen, but rather less so if a single tiny rat incisor might tell you so much. And proteomics is just getting started. And in addition to biology, there's improving imaging, inorganic materials analysis, bulk data management, robotics, and so on. Aggressive excavation, with 'DSLR, eyeball, sample bagging, brush, sift, and float', while largely unchanged for decades, seems rather more problematic if one looks ahead?
> those who used dynamite were treasure hunters, for example, not archaeologists.
This is actually not completely true. Heinrich Schliemann, for example, was widely known and criticized for destroying the ruins of Troy at Hisarlik with dynamite.
Schliemann's case is not that simple, Calvert and Schliemann's work happened before Sir Mortimer Wheeler, Tessa Wheeler and their student Kathleen Kenyon transformed it from amateur antiquarianism to the systematic professional research field we now know. As Stuart Piggott later noted "Wheeler was looking for a professional job [in Archaeology] where the profession had yet to be created".
If we follow your logic, when do we ever get to excavate anything? We can always anticipate even better technology that could capture even more information. But if we keep waiting, we'll end up with no information at all.
The article seems to suggest that the archeologists broke through a concrete barrier during routine excavations at an already heavily disturbed site without realizing that the soil underneath was anaerobic. In that case, it might be better to dig up everything as quickly as possible, since the soil is no longer anaerobic and there will be nothing to see if you wait too long.
Since at least the 1970's, there's been a trend towards the current "Archaeological Ethics, Principle No. 1: Stewardship - The archaeological record, that is, in situ archaeological material and sites, archaeological collections, records and reports, is irreplaceable. It is the responsibility of all archaeologists to work for the long-term conservation and protection of the archaeological record by practicing and promoting stewardship of the archaeological record."
And the mantra "excavation is destruction". As non-invasive archaeology advances, and technology progress in general accelerates, the range of plausibly ethical excavation seems to narrow. Towards a limit of rescue-only. Of sites threatened by whatever - looting, construction, climate change.
Or here, by surprised archaeologists. A perhaps overly-aggressive excavation for large artifacts, seems to have become a challenge of molecular archaeology rescue. And there seems no awareness of that change. Just happiness at finding well-preserved curios.
You complain about not waiting for new tech, and then complain about not using current tech. What use is future tech going to be if it's applied with the same kind of people?
Also, what kind of tech are you expecting to be developed that will be available to archaeologists? It's not like they get CERN's budget.
> You complain about not waiting for new tech, and then complain about not using current tech.
Excavation is destruction. One tries to maximize the value (by documentation, etc), and minimize the loss (by preserving samples, and leaving most of the site for future archaeologists). Minimum viable destruction. When it's an excavation of choice, and not necessity (rescue archaeology of a threatened site), what threshold of acceptability should be used, has been a subject of disagreement.
> budget
Areas with limited funding depend on the tech of others. As construction as-built documentation gets bulk incremental imaging, 3D reconstruction, and data management, so will archaeology. Same with radar mapping of ground, and of walls. As pro-ams get high-resolution multispectral imaging, so does archaeology. As molecular biology costs continue to decline by orders of magnitude, it changes biology research, medicine, ... and archaeology. And so on.
> What use is future tech going to be if it's applied with the same kind of people?
I don't quite understand the question. But one thing that changes is knowing what's valuable to retain. With pollen dating, there's effort to sample for pollen. If isolated seeds gain value in some context, or tiny fragments of bone or insects, then there's more incentive to conserve them. Grabbing samples against unknown future opportunity is done, but without knowing what it will be used for, or what properties will be needed, it's rather haphazard.
I get the impression from the article that they weren't expecting an anaerobic space: "Archaeologists lifted up a piece of concrete flooring while exploring the foundations of the fourth-century stone fortress. They were struck by a layer of black, sweet-smelling and perfectly preserved anaerobic soil in an area where it was completely unexpected".
Nod. And given rare, that could well be a reasonable standard of care. Sh*t happens. What I found disturbing was the absence, at least in this reporting, of any "but the unfortunate part of all this is...", or "we're now striving to rescue what we can". Just, "omg, excellent curios!", with seemingly no recognition of loss.
