Every year during the spring season in the old village of Santo Domingo de La Calzada, people take to the streets to honor Domingo de La Calzada Saint (1019-1109).

The "Prioress Procession" honors the saint who is said to have who helped poor people and pilgrims. Every year during the procession, ''Las Prioras'' (Prioresses) hold on their head a basket covered with white cloth and dress in black while they walk in honor of the saint. 

AP photographer Alvaro Barrientos was on assignment at this year's event and below is a gallery of his work.
