History

The area are the traditional lands of the Tongva people. Spanish missionaries who arrived in the 18th century called the indigenes Gabrieleño, because the area where they lived was controlled by the San Gabriel Mission. The Walnut area was part of the network of outlying ranches used for the grazing of cattle and sheep by the Mission.

Following secularization of the missions in the 1830s, former mission lands were divided into ranchos, and given away as land grants by the Mexican government of Alta California. In the Walnut area, the first grants were Rancho San Jose (granted to Ricardo Vejar and Ygnacio Palomares in 1837); Rancho Los Nogales (granted to Jose De La Cruz Linares in 1840); and Rancho La Puente (granted to John Rowland and William Workman in 1842). In 1868, John Rowland and William Workman divided Rancho La Puente, leaving Rowland the eastern half and Workman the western half. Rowland’s land included the western portion of Walnut and the adjacent community now called Rowland Heights. The land was used mainly for raising cattle and growing wheat, grapes, and fruit trees (mostly citrus).

In 1895, the first U.S. post office was established and given the name “Lemon”. In 1908, the post office name was changed to Walnut. As a reminder of those early days, the U.S. Post Office is on Lemon Avenue, one of the town’s main streets.

The City of Walnut’s Bicentennial Commission selected the construction of Lemon Creek Park and the restoration of the William R. Rowland Adobe Redwood Ranch House as Walnut’s bicentennial project. In 1872, the Lemon Creek Park area became the property of Sheriff William Rowland, who inherited the 29,000-acre (120 km) ranch from his father, John Rowland. The modest structure built in 1883 served as the home of Mr. Meridith, ranch foreman for William Rowland. The adobe redwood ranch house is one of the few remaining original ranch style redwood and adobe structures in the area. On October 1, 1975, the State Landmark Committee placed the W.R. Rowland ranch house in the National Registry of Historical Places.
