It’s called fairy ring. It’s like soil fungus. A fungus that indicates high organic matter content.

Maybe a structure from a previous garden is hidden below. You could dig in and see if you don’t mind a project.

Start digging maybe gold

I’d guess there used to be a flower bed there with flowers arranged in concentric circles. New soil was put only where flowers were. My aunt used to do that and it was really fascinating to see flowers come and go at different times of the years. Very eye catching.

If there is often a pool of water there, and the circles are formed of leaves and other floating or easily displaced debris, it’s likely levels at which water stayed for a bit.

Sewage tank? A buried structure of some kind would be my guess.

Fairy circle maybe? Could be a fungus infection in your yard….
First thought was large mower and a spot that usually collects water? Lot of mowers don’t double check the land for areas to watch out and monitor they’ll just rip through. So it’s a bit torn up comparatively.
Edit. Clarity.

Maybe there’s an old well underneath?

I can’t help but wonder if it’s the residual evidence of a structure? A round raised bed? It looks a little sunken to me.

There are many reasons that you can have an imprint like that which is visible in the grass.
Underground structures like a septic tank or old cistern are very possible. Could also be a big ass rock too.
An above ground reason could have been something like an old fire circle and seating area, used enough to compact the soil leaving signs to date. I think fire circle because it’s round with an inner circle, but if someone had a pool here for an extended amount of time that would definitely do the trick. Even a small above ground pool compacts the soil underneath extensively.
You could do some testing with soil cores in the area, carefully if you do suspect there’s a septic tank under there. If the soil is pretty loose compared to other areas of the yard the cause is likely underground, if it’s hard and compact the cause is likely a now absent above ground feature.

Loos like that’s where the lawnmower turns
