All that's missing is for journalists without their own knowledge to start writing posts with this UI crap.
I asked Chatgpt40 exactly the same question and got a completely different but fully argued answer. So what's true?
The photo shows an old, moss-covered stone wall in the forest above Kamniška Bistrica valley. It's the remnant of a wall that was part of the built enclosure or fence of the fužine works in Kamniška Bistrica, where Železarna Preska (known also as "Fužine v Kamniški Bistrici") operated in the 19th century.
These walls had several purposes:
Impounding and water – for diverting and retaining water that powered fužine bellows and hammers.
Defensive and protective – as enclosure around the ironworks' economic buildings.
Boundary/fencing – for protecting the industrial complex and separating functional parts (work sites, coal storage, ore etc.).
Since the fužine in Kamniška Bistrica failed already in the 19th century, today only a few walls, foundations and embankments remain, which nature has slowly overgrown – similar to what's seen on your photo.
