Answer:
Gothic architecture emerged in the 12th century and was characterized by its pointed arches, ribbed vaults, flying buttresses, and elaborate decoration. The Church of Notre Dame in Paris is an excellent example of Gothic architecture, both inside and out. Externally, Notre Dame features a number of Gothic architectural traits, including its tall spires, pointed arches, and intricate stonework. The flying buttresses, which are external arches that support the weight of the roof and walls, are particularly notable. Internally, Notre Dame is equally impressive. The nave is characterized by its tall, slender columns and pointed arches, which create a sense of height and grandeur. The ribbed vaulting that spans the nave and the aisles is another hallmark of Gothic architecture. One of the defining characteristics of Gothic architecture is its emphasis on light. This is particularly evident in Notre Dame's rose window, a large circular window made up of stained glass. The intricate tracery of the window creates a delicate, lacy effect that allows light to filter into the interior of the church.
