Cathedrals across France rang their bells in honor of Notre-Dame at night on April 17, marking two days since the devastating fire ripped through the 850-year-old Gothic masterpiece. The famed Chartres Cathedral, Marseille's Cathedral of Sainte Marie-Majeure, Cathedral of Our Lady of Strasbourg and Paris' Sacré-Coeur Basilica joined a chorus of more than 100 French cathedrals in the act of solidarity.
