French Gothic architecture
The most famous examples of Gothic architecture are found in the Île-de-France and Champagne, but other French regions created their own original versions of the style. The Angevin Gothic style in the province of Anjou features a vaults with elegant decorative ribs, as well as very ornate columns. The style is found in the interior of Angers Cathedral (1032–1523), though many of the Gothic elements of the facade were replaced with Renaissance elements and towers. A very fine example of Angevin Gothic is found in the medieval Saint Jean Hospital in Angers, which now contains the Musée Jean-Lurçat, a museum of contemporary tapestries.
French Gothic architecture
The Flamboyant Gothic style appeared in the second half of the 14th century. Its characteristic features were more exuberant decoration, as the nobles and wealthy citizens of mostly northern French cities competed to build more and more elaborate churches and cathedrals. It took its name from the sinuous, flame-like designs which ornamented windows. Other new features included the "arc en accolade", a window decorated with an arch, stone pinnacles and floral sculpture. It also featured an increase in the number of "nervures", or ribs, that supported and decorated each vault of the ceiling, both for greater support and decorative effect. Notable examples of Flamboyant Gothic include the western facade of Rouen Cathedral and Sainte-Chapelle de Vincennes in Paris, both built in the 1370s; and the Choir of Mont Saint Michel Abbey (about 1448).
