The Externsteine: Germany's Most Contested Sacred Site, Explained
What is proven at the Externsteine, what was handed down, and what was invented on purpose — plus how to visit without fooling yourself.
Thirteen sandstone pillars standing upright in a German forest, a twelfth-century relief carved into the rock face, and a round hole through which the sun rises on the summer solstice. The Externsteine are one of the most visited sacred sites in Europe and one of the most thoroughly mythologised. This article separates what the archaeology supports from what was invented — including the part that was invented on purpose.
Contents
The Externsteine are a natural rock formation of Osning sandstone near Horn-Bad Meinberg in the Teutoburg Forest, Germany. Thirteen pillars stand almost vertically because the sedimentary beds were tipped on end during mountain building. What is archaeologically secure is intensive medieval use: a Descent from the Cross relief from the twelfth century, cut chambers, niches and burials. The site's reputation as an ancient Germanic solar temple comes largely from Wilhelm Teudt's 1929 book Germanische Heiligtuemer; the excavations of 1934 and 1935, run under the Nazi regime to prove that thesis, produced no supporting evidence, and parts of the record were massaged or left unpublished. The round opening in the upper chamber is roughly aligned with summer solstice sunrise, but whether that alignment was intended is still contested. No measurable energy has ever been demonstrated at the site, and a visit is not treatment for anything.

Quick answer
The Externsteine are a natural rock formation of Osning sandstone near Horn-Bad Meinberg in the Teutoburg Forest, north-west Germany. Thirteen pillars stand almost vertically because the sedimentary layers were tipped on end during mountain building. What is archaeologically secure is intensive medieval use: a Descent from the Cross relief from the twelfth century, cut chambers, niches and burials. The site's reputation as an ancient Germanic solar temple comes largely from Wilhelm Teudt's 1929 book Germanische Heiligtümer; the excavations of 1934 and 1935, run to prove that thesis under the Nazi regime, produced no supporting evidence, and parts of the record were massaged or left unpublished. The round opening in the upper chamber is roughly aligned with summer solstice sunrise, but whether that alignment was intended is still contested. No measurable energy has ever been demonstrated at the site, and a visit is not treatment for anything.
What the Externsteine actually are
If you have only ever seen a photograph, the Externsteine look built. Thirteen slabs of pale rock stand on end in a clearing beside a small lake, some of them over a hundred feet tall, with steps and doorways cut into them. The instinct that somebody raised these on purpose is very strong, and it is wrong.
They are natural. The rock is Osning sandstone, laid down flat as sediment in the Cretaceous. When the mountain range was folded, those horizontal beds were rotated until they stood nearly upright, and erosion then stripped away the softer material around them. What is left are the hard fins, standing in a row because they were always a single bed. Nobody quarried them into position. That fact is the first thing to hold onto, because almost every claim that came later depends on the reader quietly assuming the opposite.
The site sits in the Teutoburg Forest in the German state of North Rhine-Westphalia, a landscape already loaded with national symbolism because of the Roman defeat in 9 CE somewhere in the same general region. For an American reader, the closest mental shortcut is Sedona: an unmistakably dramatic natural formation that has accumulated so many layers of spiritual interpretation that the original rock is hard to see. The difference is that at the Externsteine, one of those layers was installed by a state that wanted a particular past to be true.
The medieval layer: the part that is beyond dispute
Strip away every contested claim and something genuinely remarkable remains.
Carved into the face of Rock 2 is a Descent from the Cross relief, dated to the twelfth century and generally described as the largest Romanesque relief north of the Alps. It is roughly fifteen feet across and shows Joseph of Arimathea and Nicodemus taking the body of Christ down from the cross, with Nicodemus standing on a bent object that has generated a century of argument. Above the scene, the sun and moon appear as personified figures with cloths over their faces.
The rocks also contain cut chambers, arched niches, a rock-cut tomb chamber holding a life-size stone effigy, and stairways that end abruptly. Documentary evidence and archaeological work place a monastic or hermitic presence here in the High Middle Ages, plausibly connected to the abbey at nearby Paderborn. Grave finds have been recorded on the site.
This is the honest headline: the Externsteine are one of the most significant medieval Christian rock monuments in northern Europe. That is a big claim and it is well supported. It is also, for reasons worth thinking about, almost never the reason people make the trip.
| Claim | Status |
|---|---|
| Natural formation, not built | Established geology |
| Twelfth-century Christian relief and rock chambers | Established, dated, documented |
| Pre-Christian Germanic solar observatory | Not supported; excavations found no evidence |
| Measurable earth energy at the site | No evidence of any kind |
The sun hole, and what "aligned" really means
At the top of Rock 1 there is a small chamber, open to the sky, usually called the upper chapel. In its eastern wall is a round opening about two feet across. On the morning of the summer solstice, the sun rises approximately in line with it. The same opening is often said to frame the northernmost moonrise of the roughly 18.6-year lunar standstill cycle.
Both of those statements are, within tolerances, measurable. What they do not establish is intent. The chamber is generally dated to the medieval building phase, which means the opening is most economically explained as a window in a Christian chapel. Astronomical alignments are also easy to find after the fact: on any given morning the sun rises somewhere, and a two-foot hole accepts a wide arc of possibilities. Archaeoastronomers have measured the site repeatedly and have not reached consensus on whether the alignment is designed, coincidental, or designed for a Christian rather than a pagan calendar.
Which does not make standing there at dawn on June 21st a waste of time. It makes it what it is: watching a real astronomical event through a real hole in real rock, without needing a story about who drilled it and why.

The modern reputation of the Externsteine has a start date, and it is not ancient.
In 1929 Wilhelm Teudt, an ex-pastor and amateur researcher with no archaeological training, published Germanische Heiligtümer — "Germanic Sanctuaries." In it he argued that the Externsteine had been a pre-Christian Germanic observatory and cult centre, that the bent object beneath Nicodemus in the relief was a toppled Irminsul — the sacred pillar destroyed by Charlemagne's forces in 772 — and that the site sat on a network of straight sacred lines running across the German landscape, which he called heilige Linien.
None of this was accepted by the archaeology of the day. Specialists rejected the observatory thesis when it was published. But the book did something that professional rejection could not undo: it gave a nationalist movement a physical location. Within a few years the Externsteine had become a pilgrimage site for völkisch groups and, after 1933, an object of state interest. Heinrich Himmler's Ahnenerbe research organisation took the site under its wing. Teudt himself was made an honorary member.
The straight-line idea deserves a footnote for English-speaking readers, because Teudt's heilige Linien emerged in the same decade as Alfred Watkins's The Old Straight Track in England, which introduced the word ley. The two ideas developed separately and then fed each other. Every ley-line map sold in a gift shop today, in Germany or in Britain or in Arizona, descends from that 1920s moment.
1934 and 1935: the excavations that found nothing
Here is the part of the story that matters most, and it is the part that gets left out.
Because the regime wanted the Germanic sanctuary thesis confirmed, it funded excavations at the Externsteine in 1934 and 1935. This was not a neutral inquiry. It was a search for a specific result, by people who had already announced what the result would be.
They did not find it. The digs produced no evidence of a pre-Christian cult site. What they did produce was a documented case study in what happens when research is asked to deliver a conclusion: elements of the findings were reinterpreted to fit, portions of the record were presented selectively, and material that did not help was not published. Post-war and modern scholarship — including work by the regional archaeology service for Westphalia-Lippe — has gone back over that record and laid the process out.
So the strongest available evidence about a Germanic temple at the Externsteine is not silence. It is a well-funded, highly motivated, state-backed attempt to find one that came back empty. That is a much heavier fact than an absence of investigation would be.
None of this is a reason to avoid the place, and it is emphatically not a reason to treat everyone who feels something there as a fascist. It is a reason to be careful with the phrase "ancient Germanic," and to notice that the version of the site's past most likely to be repeated on social media is the version that was manufactured for a purpose.
Ley lines, geomancy and the modern layer
German-language geomancy — the continental cousin of British earth mysteries and American vortex culture — treats the Externsteine as a major node, a crossing point of several energy lines. Dowsers work the site regularly. So do solstice gatherings, drum circles, neo-pagan groups and a steady flow of people who simply want to sit against warm rock.
Two things are true at once here. First: the lineage of that idea runs directly back through Teudt, which is worth knowing if you are going to repeat it. Second: no instrument has ever detected a distinctive energy field at the Externsteine, and dowsing has not performed better than chance under controlled conditions. There is no measurement to argue about, because there is no measurement.
What is real, and does not require any of the above, is the effect of the place on the person standing in it. Scale, silence, cold stone, the specific quality of light in a beech forest — these do something to attention, and calling that a genuine experience costs nothing in intellectual honesty. The failure mode is the slide from "this affected me" to "therefore an ancient people worshipped here," which is exactly the slide Teudt made in print.
Visiting: how to go without fooling yourself
The Externsteine sit near Horn-Bad Meinberg, about a two-hour drive east of Düsseldorf and reachable by regional train and bus. The grounds are open landscape; the stairs and upper chapel are accessible seasonally and for a small fee, and closed in freezing conditions. The site is a protected natural monument, and climbing outside the marked routes is not permitted.
Four things worth doing
- Go early or late. Midday in summer the site is a car park with rocks attached. At 7am in October it is something else entirely.
- Spend real time with the relief before anything else. It is the single most impressive thing there and it is nine hundred years old. Look at the veiled sun and moon.
- Decide in advance what would change your mind. If you are going to test the energy claim, define beforehand what a negative result would look like. Otherwise you are only going to confirm.
- Write it down the same day. Not what it means — what happened, in order, including the boring parts. Memory of a place like this reorganises itself fast.
If you want a structure for the writing-down part, our guide to writing your own ritual is built for exactly this, and the piece on working with an astronomical event covers the same discipline for a date rather than a place.
What we don't promise
There is no evidence that the Externsteine emit a measurable energy, and no evidence that visiting a site of this kind relieves symptoms, clears blockages or heals anything. This article makes no such claim. Nothing here is medical, psychological, legal or financial advice. If something is genuinely wrong, take it to someone trained to help.
Frequently asked questions
Were the Externsteine built by anyone?
No. The pillars are a natural formation of Osning sandstone whose beds were tilted to near-vertical during mountain building and then exposed by erosion. The staircases, chambers, niches and the relief were cut into the existing rock later, in the medieval period.
Is the Externsteine sun hole aligned to the solstice?
Approximately, yes. The round opening in the upper chamber lines up roughly with sunrise at the summer solstice, and is often also linked to the northernmost moonrise of the lunar standstill cycle. Whether that alignment was intentional is disputed, and the chamber itself is generally dated to the medieval phase.
Was the site a Germanic pagan temple?
There is no archaeological evidence for it. The thesis comes from Wilhelm Teudt's 1929 book and was rejected by specialists at the time. Excavations in 1934 and 1935, funded specifically to confirm it, found nothing, and parts of that record were later shown to have been handled selectively.
What is the Irminsul in the relief?
The bent object beneath Nicodemus is widely read as a toppled Irminsul, the Saxon sacred pillar. It is a plausible and very common interpretation, but it cannot be decided from the carving itself; other art-historical readings, including a simple bent palm or tree, are equally available.
Can you visit the Externsteine, and does it cost anything?
Yes. The grounds near Horn-Bad Meinberg are freely accessible open landscape. Access to the stairs and the upper chapel is seasonal and carries a small fee, and is closed in frost. The rocks are a protected natural monument, so stay on the marked routes.
