Many years ago, a miracle has happened on the base of the hill. Miraculously, Mother Mary appeared and was seen by many locals. Thus, an image of Mother Mary was placed on the entrance part of the Hill as a remembrance of her appearance.
Ilang taong nakaraan, isang mirakulo ang naganap sa ibaba ng Hill 522. Sa milagrosa, nagpakita si Birheng Maria at nakita ng mga taong taga dito. Kaya, isang imahen ni Birheng Maria ay inilagay dito sa may entrada na parte ng tugadog bilang isang ala-ala ng kanyang pagpakita.
