Comment on 1960s theory that Stonehenge was a prehistoric computer

Would be pretty stupid to spend all this energy erecting stones just for the view of it.

Like, it obviously had SOME purpose.

What's interesting is that it may have had multiple changing purposes during construction.

It took 1500 years to be established in its current form. It's pretty likely (to me at least) that the purpose of the year 1 work was different from year 1500.

Yeah, why did they go through all that effort to build the Eiffel tower?

It honored the 100th anniversary of the French Revolution. And it demonstrated French industrial prowess, iron craftsmanship advanced engineering capabilities..

Furthermore: The Eiffel Tower was planned to be temporary, it only still stands because it was used as a radio tower.

planned to be temporary

Same for the Atomium in Brussels, Belgium.

Then they probably shouldn’t have used a stable atom..

Yet if an archaeologist excavated it with no knowledge of that, like everything that is not clearly a house, it would be chalked down as a 'ritual site'

I wonder if Stonehenge was only for demonstrating some tribe's engineering capabilities too

I realize that was tongue in cheek, but what I found more interesting is that is was only to stand for 20 years and was initially set to be demolished in 1909. So your question is even more amusing as the thing was only supposed to be temporary.

Since it was part of a World's Fair, it is unsurprising today that the Eiffel Tower was slated for demolition. I grew up very near to Balboa Park, and it was rather late in life that I learned that all those buildings were sort of hastily erected for the Panama–California Exposition, 110 years ago, and they were expected to be demolished quickly, or decay, because they were never intended for permanent habitation. And so the intervening years have been a saga of very industrious preservation and restoration, as most all of the buildings have been deemed to be architectural marvels and very much worth keeping around.

Was it unsurprising at the planning stages?

To serve as the centrepiece of the 1889 World's Fair exposition.[1]

The eiffel tower will be gone long before stonehenge.

I think the same way looking at medieval cathedrals or Roman and Greek era theatres, collesiums, and agoras...

At least the Ottomans used the Parthenon as an arms depot, giving those stones some meaning.

(This is sarcasm)

The cathedral movement started in 1006 with a quiet goal to redirect resources away from the crusades. It was also from a sort of cultural vacuum after the world didn't end at the turn of the millennium.

1006 is 90 years before the First Crusade...

It wasn't "for the view," it was, in no particular order, and non-exhaustively:

* To provide work * To serve as a reminder of the power and authority of the church * To glorify God * To make sure all the other nearby kingdoms were aware of how much cooler you are than them

* To provide work

Cite required. Work in a pre-industrial agrarian society is ever-present, unless there's a drought. (Although in that case the coffin builders may need extra hands.)

That's a simplistic, reductive, and uninformed expression of history which completely disregards the roles of the artisan, merchant, innkeeper, or any of the numerous other trades which kept early economies moving. Not everyone was a hand-to-mouth peasant farmer, either in medieval Europe, or in earlier points in history.

The building of a cathedral provided generations of employment for stonemasons, men involved in felling and shipping timber, men involved in cutting and shipping stone, as well as people responsible for feeding the workers, making and repairing their tools, etc.; and once built, the cathedral would be a draw for pilgrims, who would need places to stay, food to eat, and so on.

A cathedral provides work.

Without disregarding other lines of work, but from the neolithic revolution to the early modern times, the vast majority of the population were farmers. Quoting Brett Deveraux:

"Prior to the industrial revolution, peasant farmers of varying types made up the overwhelming majority of people in settled societies (the sort with cities and writing). And when I say overwhelming, I mean overwhelming: we generally estimate these societies to have consisted of upwards of 80% peasant farmers, often as high as 90 or even 95%." (https://acoup.blog/2025/07/11/collections-life-work-death-an...)

To elaborate: A lot of that labour was what we would term ‘strategically important’. It is well understood today the importance of stabilising demand for strategic industries (such as those involved in the construction of weapons, siege engines, warships, fortifications, et cetera). While they may not have understood it in exactly these terms, it seems that at some level keeping these people around in times of uncertain demand would have been seen as more than simple charity.

My favorite theory is that nomadic civilizations during that period were known to congregate together temporarily throughout the year.

Stonehenge was one of the places they would do this.

Makes sense to make the meeting spot nice.

Or someone told them that folks in Egypt made a huge building out of stones. They started and gave up after a while. As good a story as any?

Stonehenge is older than the pyramids though.

"Why not" is a perfectly good reason to do things, and we do things like that all the time

They even make the front page of hackernews all the time. Like spending 6 months making Doom run on a calculator

It was probably a tribe that later emigrated to Australia

Sounds like the question Ylvis posed [1], years ago. :-)
