Arch

Definition

An arch is a curved structure that spans an opening and supports weight above it, often seen in bridges, doorways, and aqueducts. The design of the arch allows for a distribution of weight across its curve, which provides stability and enables the construction of larger and more durable structures. Arches symbolize innovation in architectural design, particularly during periods when new materials and construction techniques emerged.
