A buttress is a supportive structure built against a wall to strengthen or stabilize it. In construction and masonry work, it's like an extra support or reinforcement that helps keep walls standing strong, especially in buildings that have a lot of weight or pressure pushing outward. Think of it as a triangle-shaped prop or support that leans against a wall from the outside. This technique has been used for centuries, particularly in historic buildings like churches and castles, but is still relevant in modern construction where additional wall support is needed.
