The streets of Paris look like a spiral on a Michelin map.
Another spiral is Puy de Dome.
If you draw a line from Ronsesvalles to Carignan, and line from Ronsesvalles to Puy de Dome, and line from Puy de Dome to Carignan, you have half of needle.
I do not speak French, but Aiguile is needle, I think. A_Roncevaux, A_Carignan.
If you choose Puy de Dome as a spiral, you can shoot an arrow from the Temple of Mercury (Apollo) to Waterloo or north of Cherbourg … oh yeah, bicycle tips. They don’t fit.
