History of Long Key, Isle of Youth.
Long Key was the place chosen by pirates and corsairs for brief stays and to hide the treasures conquered or ransacked during their adventures across seas and cities. One of those pirates set a cross on the coast of Key Largo as a symbol of conquest and imposition of their customs and habits. Years later, slaves running away from Spanish colonialism chose the most inhospitable places to escape from punishment.
A group of slaves ran away from the sugar cane plantations in Matanzas Province to Ciénaga de Zapata. Later on, they sailed south on canoes and found this part of land. Walking around the key, where Playa Blanca is today, they found a cross to which they offered a religious ceremony, blessing it with the rites of their gods, resulting from religious syncretism. They assigned the mission to protect this land to the cross.
