the lowest voussoir, or wedge-shaped stone, of an arch or vault that rests on the impost or support
In architecture, a springer is the lowest stone or brick in an arch where the curve begins. It is located at the point where the arch meets the supporting structure, such as a wall or column. The springer plays a crucial role in distributing weight and providing stability to the arch. This element can vary in size and shape, depending on the design of the arch, and is often made from materials like stone or brick. The springer contributes to the overall strength and aesthetic of the arch, helping to create a visually pleasing architectural feature.
