Rancho Las Vírgenes

Rancho Las Vírgenes was a 17,760-acre (71.9 km2) land grant in the Santa Monica Mountains and Simi Hills, in present day western Los Angeles County, California.

The lands of the Rancho Las Vírgenes included present day Agoura Hills, Oak Park, and Westlake Village and part of the Santa Monica Mountains.

[2] Nuestra Señora la Reina de las Vírgenes translates as "Our Lady the Queen of the Virgins".

With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.

[11] As a result of this error, the United States considered the excluded land to be part of the public domain and allowed private claimants to settle.

Many settlers may have already moved into the area by that time, in anticipation of the courts' decision, but their claims could not be documented formally until they filed for patent after 1896.
