A » The keystone is the central stone at the apex of an arch, serving a crucial role in architectural stability. By exerting pressure downward and outward, it locks all the other stones into position, allowing the arch to bear significant weight and maintain its structure. Historically, the keystone often features decorative elements, symbolizing its importance and enhancing the aesthetic appeal of the arch in architectural design.
