The sanctuary was built in honor of a rider who lost control of his horse along Calle del Cristo during a fiesta. Plunging off the top of the stone wall onto the cliffs below, the rider was said to have miraculously survived. Over the years, faithful Puerto Ricans have flocked to the chapel to pray for miracle cures and leave milagros, tiny silver charms representing parts of the body, at its altar.
Today, the chapel is a well-known yet humble historical landmark. Its gold-and-silver altar can be seen through the glass doors of the old building, but most visitors have to settle for a view from outside, as the chapel is only open to the public once a week. Since it is located within Old San Juan, the historic colonial section of the city, there are numerous ways to visit the church, including on half-day sightseeing tours, walking tours, and Segway tours.
