The Ventura Oil Field is a large and currently productive oil field in the hills immediately north of the city of Ventura in southern California in the United States. It is bisected by California State Route 33, the freeway connecting Ventura to Ojai, and is about eight miles (13 km) long by two across, with the long axis aligned east to west. Discovered in 1919, and with a cumulative production of just under a billion barrels of oil as of 2008, it is the tenth-largest producing oil field in California, retaining approximately 50 million barrels in reserve, and had 423 wells still producing. As of 2009 it was entirely operated by Aera Energy LLC.

The San Buenaventura Mission Aqueduct was a seven-mile long, stone and mortar aqueduct built in the late 18th and/or early 19th century to transport water from the Ventura River to the Mission San Buenaventura in Ventura, California. Accounts vary greatly as to when the aqueduct was built. One account indicates it was built between 1780 and 1790 by the Chumash Indians under the direction of a Spanish priest trained in hydrology. Others place its construction in the 1790s, and yet another indicates it was built between 1805 and 1815 by stonemasons brought from Mexico.The aqueduct supplied water for the residents of Mission San Buenaventura and irrigation for the mission's pasture and agricultural lands. Water from the aqueduct helped the mission flourish.Few vestiges of it remain today. Large sections were destroyed in a Great Flood of 1862, and settlers used stones from the old aqueduct to build homes. The combined effects of floods, land cultivation, neglect and land development reduced most of the aqueduct to rubble. The only significant section that remains is located at the mouth of Canyada canyon on land that was formerly known as Rancho Cañada Larga o Verde owned by the Canet family from 1873 until at least the 1960s. This remaining section is 100 feet long and ten feet high, and is believed to have "served as a siphon, drawing water uphill through conduits." The location is at 234 Canada Larga Road near the road's interchange with the Ojai Freeway.In the early 1970s, the Ventura County Cultural Heritage Commission led a fight to preserve the remaining piece, declaring it a county landmark in 1972. The following year, county supervisors voted to purchase the site. In 1975, the aqueduct site was added to the National Register of Historic Places, and in 1977 the aqueduct site was fenced off to protect it from vandalism. It was also recognized as a California Historical Landmark in 1985.A controversy arose in 1989 when a newly discovered three-foot section of the aqueduct was demolished during construction of a house. The Ventura County Cultural Heritage Board sought to prevent further demolition, and the owner built his home over the aqueduct, preserving a 20-foot-long section in his basement.In recent years, preservationists have raised concerns about the failure of the county to take action to protect the remaining section of the aqueduct on Canada Larga Road. In 1998, the Los Angeles Times wrote that "the lone surviving significant chunk of what was once the seven-mile San Buenaventura Mission Aqueduct sits forlornly in a weed-filled corner of an orchard near a freeway offramp north of the city." Though the site is owned by the county, and the head of the county's Cultural Heritage Board called it "an engineering marvel" in sore need of preservation, the county has lacked funds, and the effects of El Nino rains continued the deterioration of the aqueduct.

The Serra Cross, sometimes also known as the Cross on the Hill or the Grant Park Cross, is a Christian cross on a hill known as "La Loma de la Cruz" in Ventura, California. The site is in Serra Cross Park, a one-acre parcel within the larger Grant Park that overlooks downtown Ventura, the Santa Barbara Channel, and Anacapa and Santa Cruz Islands. According to some accounts, the first cross was erected at the site in 1782 at the time of the founding of the Mission San Buenaventura. The cross has been replaced several times, including known instances in the early 1860s under the supervision of Father John Campala, in 1912 by the E. C. O. Club, and in 1941 by the Alice M. Bartlett Club (successor to the E. C. O. Club). The site was designated as California Historical Landmark No. 113 in 1933; it was also designated in 1974 as City of Ventura Historical Landmark No. 5. In 2003, the threat of litigation over the city's use of public funds to maintain a religious symbol on city-owned land resulted in a settlement pursuant to which the city agreed to dim the lighting of the cross and sold a one-acre site underlying the cross to a private, non-profit organization that is now known as the Serra Cross Conservancy.

The Santa Gertrudis Asistencia, also known as the Santa Gertrudis Chapel, was an asistencia ("sub-mission") to the Mission San Buenaventura, part of the system of Spanish missions in Las Californias—Alta California. Built at an unknown date between 1792 and 1809, it was located approximately five miles from the main mission, inland and upstream along the Ventura River. The site was buried in 1968 by the construction of California State Route 33. Prior to the freeway's construction, archaeologists excavated and studied the site. A number of foundation stones were moved and used to create the Santa Gertrudis Asistencia Monument which was designated in 1970 as Ventura County Historic Landmark No. 11.

The Ventura County Courthouse, known since 1974 as Ventura City Hall, is a historic building in Ventura, California. It is located on a hill at the top of California Street, overlooking the city's downtown district with views of the Santa Barbara Channel and Channel Islands. It was the first building in the City of Ventura to be listed on the National Register of Historic Places and has also received historic designations at the state, county and city levels. Built from 1912 to 1913, the Neoclassical courthouse was designed by the noted Los Angeles architect Albert C. Martin Sr. in a Beaux Arts style. The building's facade includes white glazed terra cotta panels and decorations, including 24 whimsical faces of Franciscan friars, fluted Doric columns, a copper-sheathed dome and cupola, as well as Roman-arched windows. The second-floor city council chambers (previously the building's courtroom) include carved mahogany woodwork, stained glass skylights and arched windows overlooking the city and ocean. The courthouse was expanded in the early 1930s with the construction of an annex off the building's west wing. In 1968, the building was declared structurally unsound and county workers relocated. The City of Ventura purchased the building from the county and renovated it at a cost of approximately $3.4 million. The building has served as Ventura City Hall since 1974.

Elizabeth Bard Memorial Hospital, now known as The Elizabeth Bard Memorial Building, is a historic building in downtown Ventura, California. Built in 1901, it is a Mission Revival structure featuring covered terraces and a covered porch with a three-story bell tower at the southeast corner. The building was listed as Ventura Historic Landmark No. 19 in 1976 and was added to the National Register of Historic Places in 1977. After being operated as a hospital for nearly 30 years, the building was sold to the County of Ventura in 1932. It was used by the county for 44 years as offices for county officials and as a detention facility. In 1982, after being sold to a private investment group, the building was extensively renovated. The building was substantially expanded at the rear of the property, but the historic front and side facades were preserved.

The Father Serra statue in Ventura, California, representing Junípero Serra, the founder of Mission San Buenaventura, was commissioned by Ventura County through the Works Progress Administration as part of the Federal Art Project in 1935. This statue, made of concrete from a clay model by Uno John Palo Kangas, was placed in a prominent location in a public park across the street from the Ventura County Courthouse in 1936. After the Courthouse was repurposed as Ventura City Hall, the statue was designated as City of Ventura Historic Landmark No. 3 in 1974. As deterioration of the concrete statue became a concern, a wood replica was created by local carvers and used to make a bronze cast. The concrete statue was replaced by the bronze cast in 1989. The wood replica was set in the atrium of the city hall for public display. The public display of statuary honoring Serra has been a source of controversy, particularly among those alleging that Serra was responsible for the suppression of the culture of Chumash people. The city council decided in 2020 to remove the bronze statue and the wood replica from public display.
