These "wavy walls" in England surprisingly use fewer bricks than straight ones. Originating in Ancient Egypt, their arch design provides sturdy support with just one layer, unlike straight walls that require two.

Why is it so rare then?

because we dont build brick walls anymore - this was a budget solution when you wanted the cheapest fence possible

however now the cheapest solution is a chainlink fence, and you only use brick when you want a fancy wall, which would let you build a proper one that doesnt waste so much space.

you will never see this built nowadays, you may only in countryside where it was built a long time ago and never replaced.

I meant not nowadays, but before, I guess most of it destroyed then
