Damn. I used to see those in England occasionally and had no idea. I thought it was just a fancy wall. That was a pretty interesting read. Thanks for posting!

I was thinking it was a waste of material until I started reading. It makes total sense and very interesting that they’ve been used for so long…

These walls pop into my head way too frequently for having never seen one in real life

More wriggly wiggly surely?

These are done so you only need one row of bricks, which you can see in the pic. A good solution for when you you have space but not enough materials.
