…or something else?
I found this under a floor mat in the basement.

It sort of looks like an old sump pit but not completely round like the ones I see. Plus is looks like there is wood in the corner?

I agree, that is an odd shape Vince.
I believe the wood at the right radius was used for a cover support.
BTW This house is appx. 80 years.

80 years old!? It might be a closed-up man-hole cover to an old water or sewer main. Is this home very near a large town?

Back in Phoenixville, PA a fella sledge hammered bricks (like the ones in your pic) and ended up falling into the 100 year old main water line. In the past, when they built a home over top of an old man-hole cover, they’d seal it up with bricks. The bricks in your pic look old.

You could be right Nick.

I routinely see houses older than this and many times this same floor footprint has been filled with concrete. Old coal & oil fired heating units were sometimes recessed into the floor.

Thanks Keith, do you have any photos?

I found an abandoned cistern once. Does it sound hollow when you tap on it?

Yes it does Bryce.

Did you scan the area with your IR camera for clues…
