Anyone know what this iron piece is?

I found this iron piece in the backyard of a 200+ year old house. It has a perfect circle cut out. Anyone know what it was used for?

A backing plate for a through rod on a pole post or timber/rail tie my guess.

Plate dimensions, thickness, hole diameter and weight would be helpful...
