What are these stone carvings I found on a job?

I was pressure washing an old barn last week. The water revealed carved patterns on the foundation stones. They looked like circles and lines deliberately carved. In my line of work, I see a lot of old buildings. But this stuck out. What could these markings be? Maybe something from the past. I'm curious if anyone has found similar things.

Could be a bored apprentice practicing their cuts.

Hey, but aren't mason's marks usually just simple shapes? Those circles and lines could be from land surveying way back. Did you check if the property has old maps?

Mason's marks are common on old foundation stones like that.
