The Peninsula at St. Johns Center

Jacksonville covers more than 800 square miles, making it the largest city by land area in the contiguous United States — a distinction that shapes everything about daily life here. That sheer scale means neighborhoods feel distinct from one another: Riverside and Avondale offer historic architecture and an arts-forward atmosphere close to the St. Johns River, San Marco delivers a walkable, boutique-lined character near Downtown, and Southside sits near the University of North Florida and major commercial corridors. The economy runs deep, anchored by major employers like CSX Corporation, Fidelity Information Services, and Naval Air Station Jacksonville, giving the city a broad and stable employment base. Florida State College at Jacksonville adds an academic presence woven throughout the urban core.
