Rancho Cucamonga

Rancho Cucamonga is a city in San Bernardino County, United States, extending along the southern foothills of the San Gabriel Mountains. Residential neighborhoods alternate with commercial districts and industrial zones at an elevation of roughly 368 meters (1207 feet) above sea level.

The territory transformed from a Tongva settlement named Kukamongan into a Mexican land grant of roughly 5260 hectares (13000 acres) awarded to Tubercio Tapia in 1839. Later the region developed into a major wine-producing zone in southern California.

The name Cucamonga originates from the Tongva language meaning sandy place, reflecting the indigenous people who first lived in this California region. Today street names and a few historic sites recall this early settlement before European arrival.

The Superior Court of California Rancho Cucamonga District operates at 8303 Haven Avenue, providing legal services Monday through Friday from 8:00 AM to 4:00 PM. Numbered streets in a grid pattern and the mountain backdrop to the north help with orientation around the city.

Casa de Rancho Cucamonga, constructed in 1860 by the Rains family, stands as the first major California winery listed in the National Register of Historic Places. The building testifies to the long tradition of wine production in this part of California.
