Exedra of Neptune

The Exedra of Neptune is an elaborate, semi-circular architectural feature on the Pantheon’s façade in Ancient Rome. It consists of a curved niche or recess, often decorated with sculptures or inscriptions, which originally served as a prominent display space. Named after the Roman god Neptune, it symbolizes water and the sea. Architecturally, it adds depth and grandeur to the building’s entrance, creating a focal point that draws attention. Though its specific historical purpose isn’t fully documented, it exemplifies Roman craftsmanship in combining function and ornament to elevate public and religious architecture.
