Immediately, they realized that this was a sacred miracle they were witness to and they took the head of the Saint back to their homeland. Local tradition also has it that holy water springs from the rocks that mark her martyrdom. Many pilgrims visit this location and every year on 22 July, during the commemoration services for the Saint, the holy sea water in the rock pool boils during the entire Paraklisis Service; this phenomenon only occurs in the presence of a priest. If a pilgrim's faith is strong, a local tradition is that the water in the rock-pool will feel extremely warm to touch. Today there is a church on the cave of Saint Markella. The rock in which she was killed is said to spring holy water. Her nameday is on July 22  and on that day the sea is said to boil. The icon of Saint Markella is one of the most revered and is said to be miraculous. A special prayer is dedicated to Saint Markella:  Rose of piety and sprout of Chios, we honor with canticles Saint Markella who was beheaded by her father's hand, as she guarded the commands of Christ, give strength and save from danger, us who cry unto you. Glory to Him who gave you strength, Glory to Him who crowned you. Glory to Him who works through you, healings for all the faithful. Apolytikion
