The prize is conferred on prominent figures for their work in favor of international friendship and solidarity.
The cardinal, who is president of the pontifical councils of Justice and Peace, and of Migrants and Travelers, received the honor in Salerno, his native city, today, his 74th birthday.
Past winners of the award include Mikhail Gorbachev, Pope John Paul II and Mother Teresa of Calcutta.
The award was conferred on Cardinal Martino in recognition of his decades of work, first as apostolic nuncio, later as Holy See representative for 16 years in the United Nations, and at present as president of the two pontifical councils.
The awarding of the prize, attended by civil and religious authorities of the city and province, took place in the Church of the Immaculate Conception where, 60 years ago, the young Renato Martino was clothed in the habit of the Franciscan Third Order.
