Gothic architecture
Sens Cathedral (begun between 1135 and 1140) was the first Cathedral to be built in the new style (St. Denis was an abbey, not a Cathedral). Other versions of the new style soon appeared in Noyon Cathedral (begun 1150); Laon Cathedral (begun 1165); and the most famous of all, Notre-Dame de Paris, where construction had begun in 1160.
French Gothic architecture
In the 15th century, following the late Gothic or flamboyant period, some elements of Gothic decoration borrowed from cathedrals began to appear in civil architecture, particularly in the region of Flanders in northern France, and in Paris. The Hôtel de Ville of Compiègne has an imposing gothic bell tower, featuring a spire surrounded by smaller towers, and its windows are decorated with ornate "accolades" or ornamental arches. Similarly flamboyant town halls were found in Arras, Douai, and Saint-Quentin, Aisne, and across the border in Belgium in Brussels and Bruges. Unfortunately many of the finest buildings were destroyed during World War I, due to their proximity to the front lines. 
Gothic features also appeared in the elaborate residences built by the nobility and wealthy bourgeoisie in Paris and other large cities. examples include the Hôtel Cluny (now the Musée de Cluny – Musée national du Moyen Âge in Paris, and particularly the palatial house built by merchant Jacques Cœur in Bourges (1440–50). Another good example in Paris is the Tour Jean-sans-Peur, which features a Gothic watch tower and a flamboyant gothic ceiling.
