Random metal posts

[MartinB85]

Does anyone have any idea what this metal rod with a ring could be before I start digging around it?
It was covered by a foot of soil and assume it goes down at least another 2 foot,
We have about 3 of these dotted around.
It’s a 1920s house based around KD a lot of farms and fields.
Unsure if it’s and old fence post or a marker for something.

Maybe some sort of tethering post and the land has been built up around it, or ground levels have risen due to soil erosion further up the hill?

Base for a handrail post?

Used for tethering a horse near steps for easier mounting and dismounting, the ring is a lucky horseshie.
