Architectural Arch Types: Post-and-Lintel vs. Semicircular vs. Pointed Arch Explained #13515 (License: Personal Use)

The illustration contrasts three key structural systems in Western architecture: on the left, a simple post-and-lintel configuration with two vertical columns bearing a horizontal entablature; in the center, a semicircular arch composed of wedge-shaped voussoirs resting on imposts atop columns, typical of Romanesque design; and on the right, a pointed Gothic arch that directs thrust more vertically, enabling taller, lighter structures with larger windows. Each system reflects evolving engineering solutions and aesthetic priorities across centuries.
