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.
Hexafoil
A key component to Gothic architecture is a strong design principal involving geometry and harmony. The hexafoil design is implemented in various Gothic buildings constructed in the 12th through 16th century. The traditional design is used in cloisters, triforiums and stained glass windows of famous buildings such as Notre-Dame, Salisbury Cathedral, and Regensburg Cathedral. Stone cut-out hexafoils are displayed in a plate tracery style in the Salisbury Cathedral, creating a pattern along the triforium.
