Prior to its destruction, the cupola of the north tower of the Cathedral served as the front lighthouse of a pair guiding mariners into Port-au-Prince harbor.
The roof and the towers flanking the main entrance collapsed in the 12 January 2010 earthquake, although the lower parts of the walls remain standing. The earthquake also destroyed the nunciature and the archdiocesan offices, killing Archbishop Joseph Serge Miot instantly and Vicar General Charles Benoit later.
In March 2012, the Archdiocese of Port-au-Prince launched an international design competition inviting the architects of the world to submit ideas that will inform the reconstruction of the cathedral. A website www.ndapap.org was activated to promote and manage the competition.
