The Basilica of Notre-Dame de Fourvière () is a minor basilica in Lyon, France. It was built with private funds between 1872 and 1896 in a dominant position overlooking the city. The site it occupies was once the Roman forum of Trajan, the forum vetus (old forum), thus its name (as an inverted corruption of the French Vieux-Forum). Role in the history and life of the city Fourvière is dedicated to the Virgin Mary, to whom is attributed the salvation of the city of Lyon from the bubonic plague that swept Europe in 1643. Each year in early December (December 8, day of the Immaculate Conception), Lyon thanks the Virgin for saving the city by lighting candles throughout the city, in what is called the Fête des Lumières or the Festival of Lights. The Virgin is also credited with saving the city a number of other times, such as from a Cholera epidemic in 1832, and from Prussian invasion in 1870. During the Franco-Prussian War (1870–1871), Prussian forces, having taken Paris, were progressing south towards Lyon. Their halt and retreat were, once again, attributed by the Church to the intercession of the Virgin Mary. Speculating on the reasons for the construction of such an elaborate and expensive building, one author makes the statement that: "The reaction to the communes of Paris and Lyon were triumphalist monuments, the Sacré-Coeur of Montmartre and the basilica of Fourvière, dominating both cities. These buildings were erected with private funds, as gigantic ex-votos, to thank God for victory over the socialists and in expiation of the sins of modern France." Perched on top of the Fourvière hill, the basilica looms impressively over the city of Lyon, from where it can be seen from many vantage points; not unintentionally, the Basilica of Fourvière has become a symbol of the city. The Basilica, which offers guided tours and contains a Museum of Sacred Art, receives 2 million visitors annually. At certain times, members of the public may access the basilica's north tower for a spectacular 180-degree view of Lyon and its suburbs. On a clear day, Mont Blanc, the highest point in Europe, can be seen in the distance. Design and construction The design of the basilica, by Pierre Bossan, draws from both Romanesque and Byzantine architecture, two non-Gothic models that were unusual choices at the time. It has four main towers, and a belltower topped with
