Question

__________ became a venerated pilgrimage site located in mexico and named for a spanish town.

Answer 1

I believe the answer is: Guadalupe

Guadalupe is located on 241 kilometers (150 mi) off the west coast of Mexico's Baja California Peninsula.
It's built near the place of death of one of the saints, and stored a wide variety of things that predicted to be owned (or at least used) by the saint.
