About Orinda, CA

Present-day Orinda is located within four Mexican land grants: Rancho Laguna de los Palos Colorados, Rancho Acalanes, Rancho El Sobrante and Rancho Boca de la Cañada del Pinole. The area was originally rural, mainly known for ranching and summer cabins. In the late 19th century, the land was named by Alice Marsh Cameron, probably in honor of the poet Katherine Philips, who was also known as the "Matchless Orinda". In the 1880s, the United States Surveyor General for California, Theodore Wagner, built an estate which he named Orinda Park. The Orinda Park post office opened in 1888.
