Old Town San Diego State Historic Park

Old Town San Diego State Historic Park preserves the site of the first European settlement in California, established on a mesa above Mission Bay in 1769 when the Portolá expedition arrived with soldiers, missionaries, and settlers. The town that formed here grew into the commercial and social center of Mexican California's southernmost presidio district and remained San Diego's civic hub until 1872, when a fire and the relocation of commercial activity to New Town — modern downtown San Diego — ended the settlement's primacy. The park covers approximately six blocks centered on a historic plaza dating to the Mexican period of 1821 to 1848. Six original adobe structures from this era survive within the park boundaries, including the Casa de Machado y Silvas, the Seeley Stables, and the Robinson-Rose Building, which houses the park visitor center. Interpretive exhibits and period rooms within the restored buildings focus on three distinct eras: the Spanish military period of 1769 to 1821, the Mexican rancho period of 1821 to 1848, and the early American settlement of 1848 to 1872. Living history demonstrations on weekends include tortilla making, blacksmithing, and open-hearth cooking in the adobe kitchens. The park also interprets the history of the Kumeyaay people, who inhabited this region for thousands of years before Spanish arrival and whose ancestral village sites lie beneath and adjacent to the present park. Rangers lead free docent tours daily, covering the architecture, social history, and lives of women and working-class residents who are often underrepresented in official mission and rancho histories. The Whaley House, a brick Greek Revival structure built in 1857 at the park's edge, is operated separately as a historic house museum by Save Our Heritage Organisation. The park is located 3 miles north of downtown San Diego and is served by the San Diego Trolley Old Town Transit Center.
