flying buttresses

Flying buttresses are architectural support structures used in Gothic architecture to strengthen and stabilize large stone walls of cathedrals and churches. They consist of arched supports that extend from the main wall to a separate support or pier, typically positioned away from the building. This design transfers the weight and outward force of the roof and upper walls down to the ground more effectively, allowing for taller, thinner walls with large stained glass windows. Flying buttresses create an elegant exterior aesthetic while providing essential structural support, enabling the construction of soaring, light-filled interiors.
