Azkoitia was the birthplace of the mother of Saint Ignatius of Loyola, founder of the Jesuit religious order. Ignatius' maternal grandfather, Don Martin Garcia de Licona, had purchased Balda Tower in the mid-15th century. Recurring bloody encounters in the region persuaded the king, Henry IV of Castile, to reduce the tower from a fortress to a courthouse. On 13 July 1467 Don Martin's daughter, Dona Marina Saenz de Licona Balda married Don Beltran Ibanez de Onaz y Loyola from neighbouring Azpeitia in the Licona family home in Azkoitia. The original wedding contract still exists.
