Cornwall, [1] formerly known as Cornwall Station, [2] was an unincorporated community in Contra Costa County, California, [1] before it was absorbed into the City of Pittsburg. It was located 7.25 miles (11.67 km) east-southeast of Baypoint and 1 mile (1.6 km) south of downtown Pittsburg, [2] at an elevation of 39 feet (12 m) ASL. [2]

The area appears to have been named after Pierre Barlow Cornwall, an early California pioneer and president of the Black Diamond Coal Mining Company at nearby Nortonville, California from 1872 to 1904. [3] Cornwall sprung up at the intersection of two railroads, the Black Diamond Coal Mining Railroad and the San Pablo and Tulare Railroad [4] (the latter became part of the Southern Pacific system in 1888). The coal railroad crossed the San Pablo and Tulare line using an overhead trestle. [4]

A post office operated at Cornwall Station from 1881 to 1888. [2] Cornwall post office operated from 1890 to 1911. [2]

The Cornwall area, together with the nearby town of Black Diamond, was officially renamed "Pittsburg" on February 11, 1911, which may explain why the Cornwall Post Office stopped operations in that same year.

The company's mines in California and its settlement of Nortonville later became part of the Black Diamond Mines Regional Park and a California Historical Landmark. Several railroad lines were built in California and Washington to support the company's mines, and the company operated numerous ships to transport its coal. As the mines played out and petroleum became the more common source of energy, the company closed its mines and transitioned into real estate as the Southport Land and Commercial Company.
