What are flying buttreses?

Flying buttresses are architectural structures used to support the walls of buildings, particularly in Gothic cathedrals. They consist of external supports that transfer the weight of the roof and walls away from the building, allowing for taller and more slender walls with large Windows. This design not only enhances the aesthetic appeal but also improves the structural stability of the edifice. Flying buttresses are a hallmark of Gothic architecture, exemplified in famous cathedrals like Notre-Dame in Paris.
