Not modelling but could be a really small hold down for airships 

Not for experimental model aircraft in the design of fullsize aircraft?

I give up.

How about a really big clue ?

Still don't know what it is but the circle looks like it could be concrete.
Pulse jet cars maybe? Horses?
Heres an improved picture. Johns still a bit secretive.

John, as this is situated in the middle of no-where, on the coast/marsh land near Stiffkey, north Norfalk. I would think it is something to do with gunnery training. Maybe a round the pole flying target.

[John Greenfield]

Could it be a circular runway for launching aircraft / drones ?

Thats a brilliant invention, only better by the device that released the drone at the right place in the circle!!!! What period is this from, 1950's 60's or so??
