Gran Becca

If you asked a Swiss person the location of the Gran Becca, would they say on the Italo-Swiss border?

This is none other than the Matterhorn. It is known as the Mont Cervin in French and the Monte Cervino in Italian. Gran Becca is the name given to it in Aosta Valley dialect (in which region it is partly situated), the largest concentration of native speakers of a francoprovençal dialect.
