Don Bosco described in his dreams seeing multiple great European cities engulfed in flames as part of a larger vision of chastisement. Beyond Barcelona, he foresaw that cities known for their sins — particularly those which had persecuted the Church, tolerated immorality, and abandoned the faith — would be struck by fire and destruction. Italian cities would not escape, and France would suffer particularly. He connected this to the broader prophecy of the 'two columns' — where only devotion to the Eucharist and to Mary would save the Church through the tempest.
