Before colonization the area was inhabited by members of theBay Miwok people. The San Ramon Valley Branch Line of theSouthern Pacific entered service in 1891 with twoflag stops in the area that would become the City of Pleasant Hill: Hookston, located today where theIron Horse Regional Trail crosses Hookston Road, and Sparkle, where the Southern Pacific andSacramento Northern Railway intersected and today stands the Pleasant HillBART station. The area began to besuburbanized in the 1920s followingprohibition, as the many localvineyards were removed and the formerly agricultural land was subdivided for housing. Monument Boulevard was named after the Soldiers Memorial Monument to commemorate veterans and war dead ofWorld War I from Contra Costa County. It was erected on December 11, 1927, at the intersection of Monument Boulevard and the Contra Costa Highway, now Contra Costa Boulevard. The monument depicts one black and three white soldiers. It is 45 feet (14 meters) tall, constructed of formed concrete, and weighs 150 tons. In 1954 the monument was moved to its current site at the intersection of Boyd Road and Contra Costa Boulevard to make way for the construction ofState Route 21.

CinéArts "Dome" Theater, 2013
On February 21, 1967, Century 21 Theaters opened an 895-seat dome theater between Monument Boulevard and Hookston Road, just off I-680. The futuristic dome-topped cinema became an iconic landmark for the newly incorporated city.[10] The theater was designed by prolific Bay Area architect Vincent G. Raney. It had a distinctive 50-foot-high domed ceiling and oversized curved screen. The theater was initially built to showcase theCinerama widescreen process developed in the 1950s. The screen was later updated to standard flat-screen.[11] In 1973, four additional single-screen auditoriums were added to the front of the building. Renamed as Century 5 Theatres, it continued to be known familiarly as the Dome.[12]
The city hall of Pleasant Hill was designed by architect Charles Moore. Completed in the late 20th century, it has won several awards for architectural design.
For most of its history, Pleasant Hill did not have a truedowntown orMain Street. In 1991, the city began planning the redevelopment of the area around the intersection of Monument and Contra Costa boulevards. In July 2000, Downtown Pleasant Hill finally opened. The privately owned and operated outdoorshopping center was designed to resemble a typical small Main Street.
Interior of the CinéArts "Dome" Theater on its last night of operation – April 21, 2013
Starting in 2003, CinéArts operated the former Century 5 Theatres, screening primarily independent and foreign films. Due to changes in viewing habits, as many people screened movies at home, business continued to decline. The theater's property owner, SyWest Development, closed the Dome on April 21, 2013. On its last night of operation, CinéArts screenedStanley Kubrick's classic2001: A Space Odyssey.[13]
Sywest gained the approval of the Pleasant Hill City Council for its proposal to tear down the theater and redevelop the property as a two-story, 73,000+ square-foot building to house a Dick's Sporting Goods. Supporters of the theater submitted two separate appeals to overturn the approval of demolition: one by a resident of Pleasant Hill, and one by Save the Pleasant Hill Dome (SPHD) organization.[13] Both appeals were voted down by a majority of the city council; Mayor Michael G. Harris and councilmember Ken Carlson voted in favor of the appeal.[14][15][16] SyWest had the Dome demolished on May 8, 2013, precluding any further court action.[17][18][19]
On October 14, 2019, a magnitude 4.5 earthquake shook the city.[20][21]

Pleasant Hill used a system ofenvironmental planning at a relatively early stage of its modern growth. Notably the city authorized a study in the 1980s ofhillside development, which included detailed mapping ofbiota,geotechnical hazards,sound levels and other environmental constraints. These studies were used to establish appropriatezoning and development densities for all the principal undeveloped hillside areas within the city.
