The phenomenon of the Jacobean pilgrimage, was becoming even more important, and it did not make sense for the bishop of Pamplona, as head of the Church in Navarra, to alienate himself from the entry of pilgrims to this diocese. In 1127, the bishop Sancho de Larrosa, decided to create a fraternity of lay people and ecclesiastics, who managed the new hostel near Orreaga- Roncesvalles.

But the fraternity was not enough, and in 1135 a Collegiate of canons, presided by the prior Sancho, took charge of the hospital. The founder bishop gave them the incomes that were coming from the valleys nearby, as a basis for an economic and social space, which as time went by, crossed the boundaries of the kingdom. In 1137, the Pope Honorio II confirmed the creation of the chapter and its first endowment; the last step was given.
