Plaque text:

El Rancho Simi (1795)

This is the site of the headquarters of the Spanish Rancho San Jose de Nuestra Senora de Altagarcia y Simi. The name derives from "Shimiji," the name of the Chumash village here before the Spanish. At 113,000 acres, Rancho Simi was one of the state's largest land grants. Two prominent Spanish and Mexican family names are connected with the Rancho: Santiago Pico who first received the grant, and Jose de la Guerra who purchased the Rancho in 1842. Two rooms of original adobe remain, part of the Strathearn home built in 1892-93.

Plaque placed by the State Department of Parks and Recreation in cooperation with Simi Valley Historical Society. April 9, 1989.
