Simi Valley is home to two California Historical Landmarks:
NO.
939 Twentieth Century Folk Art Environments (Thematic) – Grandma Prisbrey's Bottle Village – This assemblage is one of California's remarkable Twentieth Century Folk Art Environments.
In 1956, Tressa Prisbrey, then nearly sixty years old, started building a fanciful 'village' of shrines, walkways, sculptures, and buildings from recycled items and discards from the local dump.
She worked for 25 years creating one structure after another to house her collections.
The Mosaic Walkway is embedded with thousands of treasures—tiles, shells, doorknobs, irons, car ornaments, jewelry, dishware, scissors, guns, toys — everything imaginable that creates a timestamp of 1950s post-consumer waste.
Bottle Village originally had more than 13 buildings and 20 sculptures.
Although severely damaged during the 1994 Northridge earthquake, it was placed on the National Register of Historic Places in 1996.
 It is located at 4595 Cochran St, Simi Valley.

NO.
979 Rancho Simi – This is the site of the headquarters of the Spanish Rancho San José de Nuestra Señora de Altagracia y Simí.
The name derives from 'Shimiji,' the name of the Chumash village here before the Spanish.
At 113,000 acres (460 km²), 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 José de la Guerra who purchased the Rancho in 1842.
Two rooms of original adobe remain, part of the Strathearn home built in The Strathearn Historical Park and Museum, an open-air park that is owned and maintained by the Rancho Simi Recreation and Park District, and is operated jointly with the Simi Valley Historical Society.
 The house is maintained as a historic house museum with typical period furniture and household displays.
In addition to the Simi Adobe-Strathearn House, there are various historic buildings and structures that have been moved from their original site to the park, including the 1924 children's playhouse with toys, the 1902 St. Rose of Lima Catholic Church, the original Simi Valley Library and two barns with farm tools and equipment.
 Listed on the National Register of Historic Places: NPS-78000825.
Location: Robert P Strathearn Historical Park, 137 Strathearn Place, Simi Valley.
