The new neo-classical cathedral of Saint-Vincent de Mâcon (1806-1816) was built after the Concordat of 1801, and the visit of Napoleon I and Josephine to Mâcon in 1805. The emperor granted, by decree, 240 000 francs to the city to establish a new place of worship. It was thought that this one would be dedicated to Saint Napoleon, a Corsican saint, whose feast day fell on August 15! The architect Guy de GISORS, one of the official architects of the Empire, is designated to establish the plans. By imperial decree, it is specified that the church must be erected in a neo-classical style on the site of the former collegiate church of Saint-Pierre, opposite the Place Napoléon (Square de la Paix). But the estimates were exceeded, and it was not until August 24, 1816, that the church was officially inaugurated: it was dedicated to Saint Vincent, deacon and martyr, and to Saint Louis, King of France
One of the attractions of the cathedral of Mâcon is its complete iconographic program of 19th century stained glass windows by master glass artist Jean-Baptiste Barrelon, which punctuate the nave. One of them catches the eye: the stained glass window of Saint Vincent and Saint Louis, patron saints, presenting the two Saint-Vincent cathedrals of Mâcon, the old one (the Vieux Saint-Vincent, of which only the remains remain today) and the new one, consecrated in 1816.
