Core drilling begun in 2022 revealed multiple parallel chambers, some stacked above or below others, rather than one large cavity. The chambers reach about 25 meters wide and 20 meters high, with waste layers up to nine meters thick. Salt preserved textiles, wooden bowls with food remains, human waste, and DNA from both miners and the foods they ate. By around 1200 BCE, workers were producing roughly 1.5 tons of salt a day. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much salt did ancient miners at Hallstatt produce per day during the Iron Age? By around 1200 BCE, workers at Hallstatt were producing approximately 1.5 tons of salt per day, indicating salt production had reached a large industrial scale by that period. This came after millennia of smaller-scale production that began roughly 7,300 years ago using Neolithic tools like deer-antler picks and stone tools. _daily.dev surfaces science and archaeology discoveries like this for curious readers tracking ancient technology._ ### How big are the newly discovered Iron Age salt-mining chambers at Hallstatt? The newly found chambers at Hallstatt extend at least 300 meters, with individual chambers reaching about 25 meters in width and around 20 meters in height. Several chambers run parallel to each other, some stacked above or below others, forming a large interconnected mining complex discovered through core drilling that began in 2022. _Readers following archaeological discoveries can track updates like this one on daily.dev._ ## Community take How the wider developer community reacted, aggregated from 1 discussion and 59 comments across hackernews (as of 2026-10-26). **TL;DR:** Most of the discussion drifts away from the archaeology itself into etymology of the name Hallstatt, how ancient miners lit the dark chambers, and personal travel experiences with overtourism in the town. **Sentiment:** 20% positive · 70% mixed · 10% skeptical **The case for** - Several people recommend visiting Hallstatt and nearby salt mines like Wieliczka as genuinely worthwhile, atmospheric experiences. - Commenters appreciated learning the linguistic roots of 'Hall' and 'Stadt/Statt' in salt-related place names across German-speaking Europe. **The pushback** - Multiple commenters warn that Hallstatt suffers from severe overtourism, with daily bus crowds making it hard to enjoy. - Some note the historical record is thin because Celtic miners left little writing, limiting what can be concluded about their methods. **By community** - hackernews (mixed): Conversation splits between a long etymology/spelling-reform tangent, speculation about ancient lighting methods, and travel anecdotes about Hallstatt's overtourism. **Hottest debate:** Whether English and German have had meaningful 'spelling reforms,' which spiraled into a lengthy back-and-forth only tangentially related to the find itself. **Open questions** - What exactly did Iron Age miners use for light in the chambers—torches, oil lamps, or wood splinters? - Did the Celts at Hallstatt have any form of writing that might one day surface? **Highlights** > This is one of the problems with what the Celts did: they didn't write. And they used a lot of biological material (like leather, wood) which is all gone by now. AFAIK the celts were already "gone" (assimilated / diversified into local tribes) when the Romans (which were writers) arrived. So we don't even have roman writing about the celtic customs. For example, there is are excavations around https://de.wikipedia.org/wiki/Keltenwelt_am_Glauberg and AFAIK it's still not clear if that area is mostly a castle, or if it was mostly some cultic thing -> nothing written, not even in clay or chiseled into stone. Similarly, in this article https://de.wikipedia.org/wiki/Hallstatt_(Arch%C3%A4ologie) that describes the salt mining in Hallstadt since the bronze age there is only so much that they know. So, did they use torches? They have decayed over this time. We know however that they had some kind of meat industry at Hallstein. They had plenty of salt, and so they used that to make meat durable.

There is a german wikipedia article with pictures. https://de.wikipedia.org/wiki/Kienspan Usually they used spruce wood because it does not create soot. > — [LordHeini on hackernews · 1 comments](https://news.ycombinator.com/item?id=50241004) > Hallstatt is one of these places to visit. It's topology alone is crazy, built on the edge of a mountain right above a lake. Nobody reasonable would build a city there, unless there was a really good reason for it. And the value of salt was that reason. But that topology is also the reason why a lot of the city is extremely old today. Hallstatt as a town is also affected by overtourism, especially since some Asian soap opera used it as a film location. But it is one of the places that is still worth a visit. > — [atoav on hackernews · 3 comments](https://news.ycombinator.com/item?id=50239633) > Yes it’s basically unlivable. It’s super small and way too many people want in, every day. It’s also a very beautiful spot and I sometimes crave going to that wider area (Salzkammergut). > — [manmal on hackernews](https://news.ycombinator.com/item?id=50242676) > No, it means nothing. You shall not needlessly anglicize. The name Hallstadt (not the two l letters) means Salt Town. Or, actually "place". In a lot of location names of germanic origin "stadt" doesn't the current semantics, of being a town with > 10.000. More often than not it just means "place". And "Hall" is an old term for salt. Many towns related to salt have it in their names, in many places of Germany and Austria. "Halle an der Saale" in Thüringen, Bad Reichenhall (Bayern), Hall im Tirol (Österreich), Schwäbisch-Hall (Baden-Württemberg) etc. "Hall" is believed to be of celtic origin. And the double l is important. German is a language where in the written form you look at the letters and you immediately see how it is spoken. A double vocal makes the speed slower, and a double consonant makes the speech faster. So "Halstadt" would be slow Hal (so more emphasize on the "a" instead), and "Hallstadt" would be a fast "Hall", similar in speed like the english "hell": little emphasize on the "a". > — [holgerschurig on hackernews · 3 comments](https://news.ycombinator.com/item?id=50239889) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=50200957) · 114 points · 59 comments ## Similar posts on daily.dev - [Ancient Ice Production](https://daily.dev/posts/ancient-ice-production-4jujit128) · Hackaday · 0 upvotes · 0 comments - [Historic Engineering Wonders: Photos That Reveal How They Pulled It Off](https://daily.dev/posts/historic-engineering-wonders-photos-that-reveal-how-they-pulled-it-off-lthxjstdo) · Hacker News · 1 upvotes · 0 comments - [Old Rover Data Reveals Vast Water Amounts on Mars](https://daily.dev/posts/old-rover-data-reveals-vast-water-amounts-on-mars-pvbhs2r9v) · IEEE Spectrum · 0 upvotes · 0 comments - [Unique Archeological Discovery Sheds Light On Neanderthal Wooden Tool Usage](https://daily.dev/posts/unique-archeological-discovery-sheds-light-on-neanderthal-wooden-tool-usage-nitgh3vos) · Hackaday · 0 upvotes · 0 comments - [Earth AI is vertically integrating the search for critical minerals](https://daily.dev/posts/earth-ai-is-vertically-integrating-the-search-for-critical-minerals-yvpy4mjdw) · TechCrunch · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/iron-age-salt-mining-complex-found-beneath-hallstatt-in-austria-nvul1h8ge) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Iron Age salt-mining complex found beneath Hallstatt in Austria","url":"https://daily.dev/posts/iron-age-salt-mining-complex-found-beneath-hallstatt-in-austria-nvul1h8ge","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/iron-age-salt-mining-complex-found-beneath-hallstatt-in-austria-nvul1h8ge"},"datePublished":"2026-10-26T13:42:56.308Z","dateModified":"2026-10-26T18:44:06.283Z","description":"Archaeologists have found a huge Iron Age salt-mining complex beneath Hallstatt, Austria, stretching at least 300 meters.
