The Plaza de la Inmaculada, also known as Azabachera, is where the French, Primitive, Northern, and English routes converge just outside the old Francigena or Paradise Gate. Bernardo, the church's treasurer, erected the Romanesque portal in 1122. In 1758, a fire destroyed this entryway; the Plateras now feature sculptures salvaged from the blaze. The new one was begun in 1769 by Domingo Lois Monteagudo and Clemente Fernández Sarela, who completed it in Neoclassical style while retaining some Baroque outlines from the original Baroque design by Lucas Ferro Caaveiro.

A monument of Saint James the Greater from the 18th century stands above the main front, with King Alfonso III of Spain and King Ordoo II of Portugal kneeling at his feet in prayer. The central statue represents faith.
