Legend has it that the Santuario de Chimayo, also called the Santuario de Nuestro Señor de Esquipulas, was built after a local friar performing penances saw a strange light burst from a hillside near the Santa Cruz River.
Curious, the friar sought the source of the light, which was coming from the ground. Dropping to his knees and digging in the sandy soil with his bare hands, he uncovered a crucifix, later christened Nuestro Señor de Esquipulas.
