John XXIII's announcement on 25 January 1959, in the chapter hall of the Benedictine monastery attached to the Basilica of Saint Paul Outside the Walls in Rome, of his intention to call a general council came as a surprise even to the cardinals present. The Pontiff informally announced the council under a full moon to a crowd gathered in St. Peter's square.
