I discovered rusty metal bits — perhaps ring hardware, or old trough supports. Contrary to my expectation I found under them bricks and well-packed stone, which I concluded was the original base. It was built to last.
I continued to scoop, being gentle with what I uncovered. The entire structure is solid, as if it has been waiting all these years to be rediscovered.

Why I’m Keeping It
We’re preserving it. No conversion to the utilitarian birdbath, no garden statue. It’s not going anywhere. I’m going to clean it up, put in a path, perhaps a little plaque.
Image Most people find beer-bottle caps or old broken pipes in their backyards. I discovered a hitching post and water trough from the 1790s. A real piece of history, just sitting in the grass this whole time.
