What is this crazy cover?

[spuldup]

We found this...cover... thing, by the water well head. By the edge of the woods. It is about 4 feet in diameter and heavy as hell. One can not lift it by hand. It seems to resist rust rather well. This is by an old spring house that we raized a few months ago. Nothing was underneath it. Anyone know what this was intended to do?

bird bath, flower pot, decorative architectural feature (upside down) . . . ?
Round post looks like it might attach lock in to something.

Was thinking the base of a fountain? We’d have a better idea if we saw the other side.

Lever and fulcrum time!

We have something like that here. The centre cover has a hand well pump
that still pumps water, under the cover is a dug well stone-lined. At one time
it pumped water into a trough for the horses to drink from

I think it is a bowl to fountain. See something similar..

I didn't get photos of it upside down (need the tractor to flip it) but I can say the casting on the bottom is not as precise as the side shown. As is it was meant to be presented form the side I have shown.

Bird bath was the first thought in my mind, when I saw the OP. I see that one already has two votes, so call mine third.
