A lot of previously-inhabited territory -- presumably fertile lowlands! -- was inundated as sea levels rose after the last ice age ended, around 9500-8500 years ago.
Ye auld name for that peninsula, "Jutland", implicates inasmuch.

It is truly revolutionizing our understanding of mesolithic culture.
That would suggest that oral knowledge survive thousands of years (a little more than DVDs). It's pretty remarkable.
For example, Australian Aborigines still have stories about the huge, man-eating lizards. It was considered just a standard myth until we discovered fossils of Megalania, a huge lizard matching the description, that went extinct soon after humans came to Australia.
Closer to the actual sea level rise topic, tribes of coastal northern Australia still have names and relatively precise description of land features (mountains etc) that are now underwater, but were land until 9k years ago.
Also, if you find this fascinating I suggest go watch The Exodus Decoded, www.imdb.com/title/tt0847162
Look up Black Sea deluge theory. Black sea was supposedly flooded (a bit later than the actual sea level rise from the ice melting after the ice age), around 7500 years ago, with levels rising up to 70m and turning it from a freshwater lake into Black Sea, and increasing its size 1.5x-2x.
That event is one of possible explanations for the spread of what became Indo-European language/culture/people group, which a good deal of us belong to.
Until the evidence for the Black Sea deluge was found, the Indo-Europeans were theoreticized to have come from area north of Black Sea (it is still so), but I think the initial push came from the now flooded areas.Look up Black Sea deluge theory.

Some of the metals and ceramics found in these sites are more detailed than modern day equivalents, because there was an abundance of exquisite raw materials. There is not any blatant evidence to show advanced means of manufacture, or technology hence.
Don't get too excited. From the sound of it, it could be an artefact, those could be harbour walls, but they could also be looking at some nice old karst that happens to have weathered into rectilinear shapes.
Just saying that at this stage it's all quite light on evidence.
