It is also the parish church of the oldest parish in North America, and the first church in North America to be elevated to the rank of minor basilica by Pope Pius IX in 1874.
Located on this site since 1647, the Cathedral has twice been destroyed by fire throughout the centuries. The interior was designed by Jean Baillairgé and his son François from 1786–1822. In 1843, François' son, Thomas, suggested a reconstruction of the façade to resemble the church of Sainte-Geneviève in Paris, resulting in the finest Neo-classic façade in Québec. Today's cathedral is richly decorated with impressive works of art: baldaquin, canopy, episcopal throne dais, stained glass windows, paintings, and chancel lamp (a gift of Louis XIV).
Four governors of New France and the bishops of Quebec are buried in the crypt, including François de Laval, Quebec's first bishop.
