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 Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
