Is this the last refuge of the Maglemosians?
The wiki article tells us the name Halligen comes from a Celtic word meaning salt. I'd take that explanation with a pinch of the white stuff.
Just as likely it is a remnant of what Wilkens claims was the name for the sea at the time of the Trojan war (in England) just south of the Parisii around Hull. He claims it was called the Helle sea from which the Hellenes took their own name.
What is interesting about these islands, causewayed or not, is that all living areas are built up and when the high tides come and swamp the land they are literally high and dry. Well, dryish. If they were British the government would no doubt tell them to pack up and let nature do its work, except in London of course.
Here is a video of the locals talking about their life and preparing for the flood which comes towards the end of the video. Fast forward to see how effective their defences are and simple if you can't be bothered to watch it all the way through. It is all in German which may cause problems for some although really it doesn't matter as it's easy enough to work out what's going on.
Did the original inhabitants of Doggerland resort to similar methods to protect their own lands and homes all those years ago?
