“The ancient inhabitants of Scotland were building artificial islands...”

Interesting

artificial islands = defendable position - easier than digging deep moats on rocky ground.

I’m guessing as the water continued to rise they just kept piling the rocks up over the years/centuries? Of course that meant starting off with a 10 acre island and ending up with a 3 acre one.

And maybe the sacrifices were to the ocean God. “Okay - give it a pot so it doesn’t take anymore of our land!”
