As former agricultural land was subdivided for housing, the region started to be developed in the 1920s. Monument Boulevard, which was built on December 11, 1927, was named after the Soldiers Memorial Monument to honor World War I troops. One black and three white troops are depicted in the monument. Built of shaped concrete, it is 45 feet (14 meters) tall and weighs 150 tonnes. The monument was shifted to its present site on Boyd Road and Contra Costa Boulevard in 1954 to make way for the forthcoming building of the highway.
Developed largely in the years after World War II, it was not until 1948 that the area had a post office. In 1961, the town was established.
Century 21 Theaters opened a 895-seat dome theater between Monument Boulevard and Hookston Road on February 21, 1967(I-680 was later built west of here). The futuristic dome-topped cinema, visible from the freeway after it was built, became an iconic landmark for the newly incorporated city. The theater was designed by prolific architect Vincent G. Raney from the Bay Area. It had a unique 50-foot-high domed ceiling and a curved screen that was oversized. Initially the theater was constructed to display the widescreen process created by Cinerama in the 1950s. The screen was subsequently updated to the flat-screen standard.
