Fillmore is a city in Ventura County, California, United States in the Santa Clara River Valley. In an agricultural area with rich, fertile soil, Fillmore has a historic downtown that was established when Southern Pacific built the railroad through the valley in 1887. They also provided a name for the town; J. A. Fillmore was a general superintendent for the company’s Pacific system. In 1769, the Spanish Portola expedition, first Europeans to see inland areas of California, came down the valley from the previous night’s encampment near today’s Rancho Camulos and camped in the vicinity of Fillmore on August 11. Fray Juan Crespi, a Franciscan missionary travelling with the expedition, had previously named the valley Cañada de Santa Clara. He noted that the party travelled about 9–10 miles and camped near a large native village. Founded in 1887 upon the arrival of the Southern Pacific Rail line, the city voted to incorporate in 1914. Fillmore sits at the foot of Topatopa Mountains and several other mountains in the Santa Clara River Valley. It is famous for its many orange groves.
