Gothic architecture
Introduction
Paris is the birthplace of Gothic architecture. During the reign of Louis VI of France (1081-1137), Paris was the principal residence of the Kings of France, Reims the place of coronation, and the Abbey of Saint-Denis became their ceremonial burial place. Suger who is a counselor of Louis VI and Louis VII, as well as a historian, he oversaw the reconstruction of the ambulatory of Saint-Denis, making it the first and most influential example of Gothic architecture in France. [4] Gothic architecture was used for abbeys, churches, castles, palaces, town halls, universities, and private dwellings. Gothic cathedral usually is the landmark with tall spires and surmounted one or two pinnacles higher than other buildings in the town. Gothic architecture evolved from Romanesque architecture and supplanted by French Renaissance architecture. There are some common elements such as the flying buttress, pointed arch, ribbed vault, and verticality. Gothic architecture is historically divided into four periods, Early Gothic from 1130-1230, High Gothic from 1230-1330, Rayonnant in 14th Century, Flamboyant in 15th Century, or Late Gothic in 16th Century.

Early Gothic
The Early Gothic evolved from Romanesque architecture, it adopted a pointed arch, the ribbed vault and focused on the height of the walls and ceiling. To heighten the walls, designer divided into four layers, arcade, gallery, triforium, and clerestory. Another new significant invention was adding the new elements verticality to the façade. The Notre Dame Cathedral is the best example, the name means “Our Lady” in French, and it was the first gothic cathedral and the first building to use flying buttress in the world. [III] This painting by Jean Froissart in 1475. The background architecture is the famous Cathedral of Notre Dame, it documents Arrival in Paris of the young Duke Louis II of Anjou and his mother Marie de Blois arrived in Paris, and a lot of citizens were welcoming in the 15th century.[IV] Originally, it was not supposed to design of flying buttress, but after the construction of the cathedral began, the thinner walls grew ever higher and stress fractures began to occur as the walls pushed outward. The cathedral's architects, in an effort to fix the problem, built supports around the outside walls, and later additions continued the pattern. [5] Flying buttress is a special type of buttress, they are buttresses on the building’s exterior, and used to transmit horizontal thrust of a vault across an intervening space. The name “Flying buttress” is come from the figure, the buttress looks like flying through the air instead of resting on the ground. The purpose of using the flying buttress is to provide the horizontal support of a wall. Generally, the upper parts of the buttress are carried by the majority of the load. So changing buttress to a semi-arch shape provides the same bearing capacity, costs less money, and adds aesthetic decoration. Furthermore, the load bearing walls can be cut-outs, like large window will weaken the load of thick wall.

High Gothic
The high Gothic style continued following the initial rule and improved to make the new cathedrals taller, wider, and lighter. Four layers reduced to three levels, and the gallery was dropped out. Also, clerestory altered from a single window to a pair of windows and connected with a rose window in the middle. The construction of the Chartres cathedral is a good representative one.[V] At Chartres, the exterior of it was constructed by the heavy flying buttresses which increase arcades, nave, and the size of the window. The rib vault changed from six to four ribs, quadripartite make the vaulted ceiling simpler and stronger. Under the satisfaction for both proper logical structure and aesthetics perspective, Chartres completed a big breakthrough of the architectural history which solved the problem of how to arrange a shift in shafts around a pier in a way. This design called “ pilier cantonné”, it means a clustered column or pier which consists of a central mass or central pole. The pilier cantonné of Chartres has four slender columns attached to a large central core that support the nave arcade and aisle vaults. This design is very influential and also featured in other high gothic architectures.

Rayonnant
Rayonnant and Flamboyant are both originated from High Gothic architecture, but its builders were more focus on the decorative aspects and the practical use of spaces. The tendency of Rayonnant is ponderability and vertical emphasis, shafting stained glass instead of masonry in the design of the structure. The Rayonnant style innovated window design which mixed glass and window glazing. They used larger windows and introduced glazed triforia, as well as a significant change in the window tracery design – the windows were no longer framed by plates but appeared as if they were gently touched by thin bars. [6] Glazed triforia is a new invention of the Rayonnant period, the tradition of the triforium in the cathedral from an Early or High Gothic that was a dark band in the hallway and divided the top of the arcade from the clerestory. The Abbey Church of St Denis is changing sloping lean-to roof over the side aisles to double-pitched roofs over the aisles for draining off the rain. So the Architects glazed the outer wall of the triforium and inner wall lessen to thin bar tracery. [VI] Comparing to another earlier cathedral like Amiens Cathedral that windows are framed by stone and occupied only a portion of the wall, Notre Dame Cathedral has two rose windows on the north and south of the transept and occupied the entire space between the pillars.

Flamboyant
In addition to, Flamboyant is also called late Gothic period and created with luxuriating decoration for notables or wealthy citizens with ornamented windows. There are other new features included lacy ornaments, multiple buttressing, stone pinnacles, and the window decorated with an arch. The focus has still remained the inside unity, such as the illumination exploration. Suitable examples of Flamboyant Gothic is Rouen Cathedral. [VII] Lastly, there are some new techniques like the stained large windows, glazed triforia, pilier cantonné, high ceiling, and the light inside the cathedral also influence modernism.
