What would a ring this size be used for?

[Beeps in my sleep]

I was detecting next to a very old barn today and found this big ring. What would a ring this size have been used for or how old could it be? I was thinking to tie up horses?

Can you describe the rings? Diameter, metal they're made from, shape, thickness of the metal, ect.
