Cathedral of Our Lady of the Assumption, Roman Catholic cathedral in Port-au-Prince, Haiti

The Cathedral of Our Lady of the Assumption is a roofless stone church in downtown Port-au-Prince, its upper walls broken away and rubble piled inside. The central facade rises in tiers above three arched entryways, with a circular rose window framed by a wide arch. The 2010 earthquake collapsed the roof and the two towers flanking the entrance, though the lower walls remain standing.

Construction took place between 1884 and 1914, making this the principal Catholic church in Haiti for over a century. The 2010 earthquake caused major destruction and marked a turning point in its story.

The cathedral's name refers to the Assumption of Mary, and its dedication was celebrated on 13 December 1928, fourteen years after the 1914 consecration. A Cavaillé-Coll organ was installed in 1923, and a carillon of four bells weighing 4,763 kg was hung in 1921, cast from the metal of the earlier bells. The transitional cathedral behind the ruins was consecrated in 2014.

The cathedral sits at the corner of Avenue Mgr Guilloux and Rue Pavée in downtown Port-au-Prince and is accessible by public transportation. Visitors should check current site conditions before planning a visit.

The north tower's cupola once served as the front lighthouse of a pair guiding mariners into Port-au-Prince harbor. The 2010 earthquake brought down the roof and both entrance towers, but the lower walls and parts of the nave pillars still stand. In 2012 Puerto Rican architect Segundo Cardona won the reconstruction competition with a design that frames the surviving facade between two new concrete towers.
