# Byron, California

Byron is a census designated place (CDP) in Contra Costa County, California, United States.

## History

Byron's location was part of a land grant that Jose Noriega received from the King of Spain in 1835. Noriega then sold 17,000 acres to John Marsh for the equivalent of $500 (three U.S. cents per acre). In 1841, the Bidwell-Bartelson wagon train arrived at Marsh's ranch with the earliest Anglo settlers from the east.
Byron's first post office opened in 1878. Byron is named after an employee of the San Pablo, and the eastern U. S. and Pacific Railroad.
In 1942, all of the town's residents of Japanese descent were forcibly removed by the US government with pressure from California agricultural interests and taken to Turlock assembly center.
In 1960, Contra Costa County built the Orin Allen Youth Rehabilitation Center, better known informally as the Boys' Ranch on a 50 acres (200,000 m$^2$) tract immediately southeast of Byron. The Boys' Ranch is a minimum-security facility that houses up to 100 youthful offenders. The property has no security fence to contain residents within the perimeter and includes dormitories, classrooms, a kitchen and dining facility, athletic facilities and administrative offices which occupy about one-third of the area. Its objective was stated as rehabilitation, rather than simply detention.
In 2008, a Contra Costa County Grand Jury began an investigation into whether the facility was cost-effective, or whether it should be permanently closed. It began by conducting an unannounced site inspection in September, 2008. In 2009, it released its report to the county commissioners. The report identified 21 defects at the facility that needed correction.

## Former resort

37°50′54″N 121°38′00″W﻿ / ﻿37.84833°N 121.63333°W﻿ / 37.84833; -121.63333 Byron, California is also home to the somewhat well-known and historical Byron Hot Springs, a now-abandoned resort that was a retreat that attracted many movie stars and famous athletes in the early 1900s. The first hotel was built around 57 hot springs and owned by Lewis Mead in 1889. The hotel included a three-story wood building, with a few cottages scattered nearby, as well as a laundry, gas plant and ice plant, all of which were destroyed by fire on July 25, 1901. A second hotel, also three stories, but made of stucco was constructed 1901–1902, but it burned on July 18, 1912. The third and final hotel, a four-story brick structure was built in 1913, reopened in 1914.
In 1938 the resort closed, after a series of lawsuits that were probably brought about by the Great Depression, but was leased by the government in 1941 and became a military interrogation camp housing both German and Japanese prisoners of war, known as Camp Tracy, until 1945, when orders were sent to dismantle it.
In 1947 Byron Hot Springs was put up for sale and purchased by the Greek Orthodox Church for $105,000. It served as Monastery St. Paul for several years. It then changed hands several times as a resort, country club, and private residence. In 2008, a developer announced plans to restore the resort. As of 2021 a Byron Hot Springs website retains a "Resort Plans" page for the restoration of Byron Hot Springs.
In 2005, a Victorian-era carriage house on the property was burned to the ground. The hotel itself sustained some fire damage, but still stands.
Byron Hot Springs is 1.5 miles (2.4 km) south-southeast of Byron. A post office operated at Byron Hot Springs from 1889 to 1930.
