PARIS—Bells of cathedrals across France rang in a moving tribute on April 17 to Notre Dame as firefighters and experts continued to keep the beloved but weakened landmark under close surveillance.
From Sacre Coeur in Paris to the cities of Strasbourg in the east and Rouen in the west, the architectural treasures of France solemnly marked the inferno, two days after it ravaged the gothic cathedral, widely regarded as the soul of France.
