A triumphal arch is a monumental structure built to commemorate significant events, victories, or individuals. These arches often feature decorative elements and inscriptions that celebrate achievements. They are typically constructed from stone or brick and can be found in various cultures around the world, with the most famous examples originating from ancient Rome. Triumphal arches serve both a decorative and functional purpose, often acting as gateways or markers in urban landscapes. They symbolize power and glory, reflecting the values of the societies that built them. Notable examples include the Arc de Triomphe in Paris and the Arch of Constantine in Rome.
