It is also registered as California Historical Landmark #362.","why_significant":"The adobe is tied to early San Fernando history: it was first used by pioneer Eulogio De Celis, stands on former Mission San Fernando land, and may incorporate part of a mission building. It was enlarged in 1853 by Romulo Pico and restored in 1929 by Dr. Mark Harrington. The form values it as an authentic example of a composite mission and Hispanic California ranch house.","narrative":"This restored adobe at 10940 Sepulveda Boulevard in Mission Hills began in the Mission era and was first used by Eulogio De Celis, a pioneer of the San Fernando area. It sits on land once owned by Mission San Fernando, and the form suggests part of the original structure may have been a mission building. Romulo Pico, son or adopted son of Andres Pico, acquired the property in 1853 and enlarged it. After falling into ruin, it was carefully restored in 1929 by Dr. Mark Harrington, who aimed for authenticity. The main portion measures about 75 by 25 feet, with two wings, clay tile and wood floors, tile roofing, and iron grills at doors and windows. Later it served as a YMCA headquarters before the City of Los Angeles acquired it through the efforts of the San Fernando Historical Society. A 1971 earthquake damaged the walls and made the house unsafe to occupy until repairs are completed.","period_of_significance":"19th Century","architect_builder":null,"architectural_style":"Composite mission and Hispanic California ranch house","criteria":[],"status_note":"Good condition, restored and altered, on its original site, used as a museum and park and owned by the City of Los Angeles.
