Old Palo Alto, located between University Avenue and Embarcadero Road, is a historic and residential Palo Alto neighborhood with tree-lined streets and landmark architecture. The neighborhood’s character concentrates around University Avenue at Emerson Street, where sidewalk patios, independent boutiques, and gallery-style storefronts set a polished, walkable rhythm. Architectural cues run from early 20th-century Craftsman and Spanish Revival homes to carefully updated estates behind mature oaks. Gamble Garden adds a quiet, horticultural counterpoint to the street grid. Community touchstones include Stanford Theatre, Palo Alto Art Center, and Kepler’s Books. Caltrain at Palo Alto Station links the area to the Peninsula corridor.
