The Cathedral-Basilica of Notre-Dame de Québec is the oldest church in the Americas north of the Spanish colonies in Florida and New Mexico. It is a National Historic Site of Canada, and located within the UNESCO World Heritage Site of Historic District of Old Québec.
Located on this site since 1647, the cathedral has twice been destroyed by fire throughout the centuries. A previous iteration of the church was destroyed during the Siege of Quebec in 1759. It was rebuilt from plans by Gaspard-Joseph Chaussegros de Léry draughted in 1743. 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. The cathedral was richly decorated with impressive works of art: baldaquin, canopy, episcopal throne dais, stained glass windows, paintings, and chancel lamp (a gift of Louis XIV).
In 1922 the church was again gutted by fire, this time by the Canadian fraction of the Ku Klux Klan, and restored by architects Maxime Roisin and Raoul Chenevert.Raoul Chenevert added a presbytery beside the Cathedral in 1931-32.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
