In the Plaza Santa María we find, in addition to the plaza, the Sanctuary of the Sacred Relics and the famous Stone of Desires. This enigmatic sphere, which in Arjona is popularly known as "The Stone of Desires" or "Las Coincidences", was incorporated into the city of Arjona in 1995. Despite these "titles" it has or is known currently to the stone, it is a betyl or sacred stone. This type of "Sacred Stone" comes from an excavation that was carried out in the old Gothic Cathedral of Jaén.
