It is a group of 19th-century ranch buildings: an adobe residence, a limestone residence and limestone outbuildings.","why_significant":"The de la Osa Adobe is described as a surviving example of Hispanic adobe influence on the pioneer American period in pastoral California. The Garnier Residence is an eclectic ranchhouse that reflects the personal taste of its owner-builder, Eugene Garnier, although the form says documentary support for its alleged history is meager. The form also says research is still needed to determine the true place and significance of the buildings.","narrative":"Los Encinos State Historic Park in Encino preserves the remains of Rancho El Encino, a 19th-century ranch in Los Angeles County. The best-known building is a one-story adobe ranchhouse, about 20 by 150 feet, built in the 1840s by Don Vicente de la Osa with porches along both long sides and one end. Its roof was later changed from flat asphalt to sloped shingle. Nearby stands a two-story limestone residence in a Provincial French manner, built around 1872 by Eugene Garnier, a Basque who turned the property into a large sheep ranch. Two limestone food-storage buildings and a herder's hut complete the group. Later owners kept using the adobe as a residence, and it also served for a time as a stagecoach stop. The property was listed as an example of Hispanic adobe building in pioneer California and of an eclectic ranchhouse shaped by its builder, though the nomination notes that more research is needed on the buildings' history.","period_of_significance":"19th Century (circa 1840s for the de la Osa adobe; circa 1872 for the Garnier residence)","architect_builder":"Don Vicente de la Osa (adobe); Eugene Garnier (Garnier Residence)","architectural_style":"Hispanic adobe ranchhouse; Provincial French (mid-19th century) for the Garnier Residence","criteria":[],"status_note":"Owned by the State of California and used as a park and museum.
