The Vallejo Flour Mill in Fremont, California, was built in 1850 by José de Jesús Vallejo, elder brother of General Mariano Guadalupe Vallejo on his Rancho Arroyo de la Alameda. A second flour mill was built in 1856, the stone foundation of which may still be seen today.
The town of Niles, California (now part of Fremont, California) was once called Vallejo Mills, after the Flour Mill. The stone aqueduct built to carry water for the mill parallels Niles Canyon Road (State Route 84) . The mill is located at the intersection of Niles Canyon Road and Mission Boulevard (State Route 238) in Vallejo Mill Historical Park and is a California Historical Landmark (#46).
