An almost perfect triangular Relationship exists between Stonehenge, Foel Drygarn, Lundy, Guernsey, Gerring le Loc'h, Golden ratio and Pi as evidenced in this overview and geometric constructions clarifying the underlying mathematical logic and intent.
There are many more such figures, this one is not the best one to date, but the third to biggest one I know of.
The largest one is far more interesting as it highlights knowledge of spherical geometry in the most subtle and refined approach.
Any comments ?
Thanks for feedback 
Further explannations :
I'm sorry, I hadn't realised this Forum is essentially Anglo Saxon, and user's don't easily relate Km to customary Mile system.
Maybe a little clarification will help understand...
A simple device to convert Km to Miles: just divide the actual Km distance by ϕ to get a good ½% error approximation.
This because 1 mile = 1,609344 Km, almost 1,618 or ϕ Km.
So, would have 1 Mile = ϕ Km as should have been, the radius of the earth would have been :
2/πϕ 104 Miles or 2/πx104 Km as presently is (with negligible error).
Actual standards have diverged for number of reasons, but both standards stem from same source.
It could be this conversion Miles to Kilometres has passed unnoticed, but it is however of great importance to understand the history of our present day standards, and where they came from, and reasons why can be found in remote areas such as Guatemala Tikal pyramid..
The correlation between the two standards can be understood reading accounts of 17th century Livio Burattini, Jhon Greaves and John Wilkins associated on a time line.
It's really worth looking into, but outside this Forum's context.
If not entirely convinced, a glance at the Kheops pyramid will highlight the same relation between apothem and base of the Pyramid.
Up to you to verify...
