San Dimas is a city in Los Angeles County, California. Located in the San Gabriel Valley the history of this area dates back to the 1830s and the Rancho San Jose land grant from Governor Juan Bautista Alvarado in 1837. The land included the present day cities Pomona, Claremont, San Dimas, Glendora, and La Verne. The city took its name from San Dismas Canyon in the San Gabriel Mountains above the northern section of present day San Dimas which is named after Saint Dismas, the repentant and crucified thief.
The city has a rich history from the first known European exploration of the area in 1774 to over 8,000 years of settlement by the Tongva Native Americans. While the city’s ranch lands changed hands many times, it was the arrival of the Santa Fe Railroad in 1887 that first mapped what was then known as La Cienega Mud Springs. This boom resulted in development of streets, the opening of small businesses and soon the birth of what is now known as San Dimas. Like much of the surrounding area, citrus groves were the main crop and business in San Dimas until the mid -20th century.
