Arch crown, also known as a keystone, is a decorative and functional element used in masonry construction to complete an archway. It is typically made of stone, brick, concrete, or other materials and is placed at the top center of an arch. The arch crown serves as a crucial component of the arch, as it locks the other stones or bricks in place, providing stability and preventing the arch from collapsing under its own weight. The arch crown is designed to bear the weight of the arch and distribute it evenly to the supporting pillars or walls on either side of the archway. It also helps to counteract the outward pressure of the arch, which can cause the arch to collapse. The arch crown is often the last piece of the arch to be installed, and its shape and size are carefully calculated to ensure a perfect fit. In addition to its functional purpose, the arch crown is also an important decorative element in architecture. It is often elaborately carved or decorated with intricate designs, adding to the overall beauty of the archway. The arch crown can also be used to convey symbolic meaning, such as in religious architecture, where it may be adorned with religious symbols or figures. Overall, the arch crown is an essential component of archway construction, providing both structural stability and aesthetic appeal to the architecture. Its design and placement require careful calculation and attention to detail to ensure a perfect fit and proper function.

Arch crowns, also known as keystones, are a decorative masonry element that is used to complete an archway. They are typically constructed out of stone, brick, concrete, or other materials and are used to improve the aesthetic of the archway while increasing its stability. In the past, the arch crown was placed in the center of an archway and was used to support the weight of the arch above it. The arch crown was also used to offset the outward pressure of the arch and to create a tighter fit between the two halves of the arch. In modern times, arch crowns are often used for decorative purposes only, as their structural purpose is no longer necessary.
