Piedras Albas

Means "white stones" in Spanish (the second word only used as a Latinism or in a poetic/literary sense, in place of blanca), taken from the titles of the Virgin Mary, La Virgen de Piedras Albas and Nuestra Señora de Piedras Albas, meaning "The Virgin of White Stones" and "Our Lady of White Stones" respectively.
She is the patroness of El Almendro in the Andalusian province of Huelva.
