Archaeologists off the coast of Brittany, France, have discovered a 394-foot wall beneath the waves.
The threshold of solid stone, which could date back to 5,000 BCE, may just show what happens when humans try to build walls to block the ocean’s might.
The wall is believed to have been built for catching fish or protecting people from destructive seawater, according to the BBC.
At around 66 feet wide and seven feet high, the solid 3,600-ton mass of stone has lasted for about 7,000 years, per the researchers, who believe it to have been constructed in the context of a Stone Age community of hunter-gatherers.
While the wall would have been well-situated on the shoreline when in use, it is now 30 feet underwater.
If we look at the average of 6-8 inches of sea rise per century over the last 8,000 years we’re looking at 35-46 feet of sea rise. And the rising seas from the great pulsewater melt started filling the Med. Of course, here we go
With big risks posed by ever-rising seas, discoveries like this one help to demonstrate how coastal communities could one day disappear beneath ocean waters.
Those who built the wall may have put it up to try and mitigate a rising tide in their own time.
In its coverage, the BBC cited a paper published in the International Journal of Nautical Archaeology. “The submersion caused by the rapid rise in sea level, followed by the abandonment of fishing structures, protective works, and habitation sites,” according to the paper, “must have left a lasting impression.”
Driven by human activity — namely, the burning of polluting fuels — which is contributing to the overheating of the planet and the melting of glaciers, sea levels are now consistently reaching all-time highs. Their impacts are already being felt, particularly in vulnerable coastal and island communities.
What caused the big sea rise back then?
People can take steps now to lower their contributions to the pollution that is heating the planet and driving rising seas. And these can look like everything from avoiding fuels such as oil and coal to exploring plant-based diets.
Oh, piss off.
Anyhow, the wall is pretty cool. And, I suspect if the lost city of Atlantis is real it most likely was swallowed up by the same rising Med along with subsistence from earthquakes.
The actual paper… Submerged Stone Structures in the Far West of Europe During the Mesolithic/Neolithic Transition (Sein Island, Brittany, France)… did not speculate about climate change but did mention that the sea wall(s) were “possibly protective”.
Abstract
Morpho-tectonic analysis of LIDAR data off Sein Island (France) revealed 11 submerged structures at significant depths. Dives conducted between 2022 and 2024 confirmed these are human-built granite structures, with the largest wall measuring 120 m long. Some structures appear to be fish weirs, others possibly protective. Based on relative sea level data, the dating of these structures was estimated to range from 5800 to 5300 BCE. These remains, unique at such depth, show Mesolithic human presence and advanced building skills, predating Neolithic megalithism in Brittany by 500 years. They offer valuable insight into maritime hunter-gatherer societies during the Mesolithic–Neolithic transition.

And yes, CO2 is increasing from our burning of coal, oil and gas. And yes, CO2 is a potent greenhouse gas and is responsible for the current bout of global warming. And yes, trumpinc wanted to build a seawall to protect a golf course from Atlantic storms.
Neolithic Frenchmen could build a seawall but Donald trump couldn’t! LOL.
In a brief response to the Rimjob rant let’s go to AI.
So Rimjob do you enjoy making a fool of yourself? LOL
Overreact much, CumBrain? Have you seen a doctor?

The CURRENT sea level rise is about twice that average rate reported by Teach and the RATE OF CHANGE is increasing he seems unable to acknowledge that.
Also sea level is not level. The sea level is not universally level all over the planet. That is why we must have locks in the Panama canal
Everyone knows the city of Atlantis was a spaceship that flew to the Pegasus galaxy. There was a series of documentaries on this.
