Right down the hill from Universal Studios, Hollywood is a preserved historic site that is probably one of the most important sites for California and the United States. Campo de Cahuenga was an adobe ranch house where the Treaty of Cahuenga (also known as “The Capitulation of Cahuenga”) was signed between Lieutenant Colonel John C. Fremont and General Andrés Pico on January 13, 1847, ending the fighting in the Mexican American War.
