The University of Georgia Arch is located on the North Campus. It is the cast-iron gateway that stands at its main entrance. Known as "The Arch" (but often erroneously pluralized to "The Arches"), the structure was patterned after the Seal of the State of Georgia, and has faced historic downtown Athens ever since it was erected in the 1858. Although the Seal's three pillars represent the state's three branches of government, the pillars of The Arch are usually taken to represent the Georgia Constitution's three principles of wisdom, justice, and moderation, which are engraved over the pillars of the Seal.
