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.
Gothic architecture
The next period was termed "Rayonnant" ("Radiant"), describing the tendency toward the use of more and more stained glass and less masonry in the design of the structure, until the walls seemed entirely made of glass. The most celebrated example was the chapel of Sainte-Chapelle, the chapel attached to the royal residence on the Palais de la Cité. An elaborate system of exterior columns and arches reduced the walls of the upper chapel to a thin framework for the enormous windows. The weight of each of the masonry gables above the archivolt of the windows also helped the walls to resist the thrust and to distribute the weight.
