References to the cave (Spanish: "cueva") are found in the original plans of the castle. When the current owner, Professor Michael A. Popp, acquired the estate, he made it his mission to reveal the secret. On the slopes blessed by the angel, he re-cultivated the old areas of the Majorcan farmers and christened the terraces he created the "Stairway". In the event that he discovers the cave, a wine is to be made there. The name is already fixed: "Cueva Madonna".
