Some other caminos, roads, etc, via the Pyrenees:
Portalet, Palo, Camino de Benasque (where 3 diff hospitals were constructed through history, indicating its importance), Bujaruelo via the Puerto de España, Brecha de Rolando, Pineta to Biescas.
3 meet at Ainsa: one comes on the right,the left one is now a tunnel.
There's another one that comes from Lourdes via Bujaruelo. It has has thwo roads: via Monegros on to Zaragoza, and from there by the R. Ebro to Logroño.
There is another road, parallel to the Pyrenees, that reaches Sabiñanigo, leading ultimately to Jaca by way of another one, Benasque.
There are other caminos, like the Puerto del Palo.
And then half a dozen minor ones.
These names were pilgrim, cyber, contributions.
From this we may conclude that there were in fact many caminos to Compostela through the ages, via the Pyrenees, not just through Roncesvaux & Somport.
Best,
