History

Mariposa County was one of the original counties of California, created at the time of

statehood A state is a centralized political organization that imposes and enforces rules over a population within a territory. There is no undisputed definition of a state. One widely used definition comes from the German sociologist Max Weber: a "sta ...

. Thus, Mariposa County is known as the "Mother of Counties". Mariposa County's original seat was a now-nonexistent hamlet known as Agua Fria (Spanish for "cold water"), about 3 miles directly west of Mariposa proper on Agua Fria Road, which runs from Highway 140 to the south, to the community of Mt. Bullion to the northwest. Charles Fremont moved the county seat to Mariposa in 1854, resulting in the construction of the Mariposa County Courthouse, whose grounds occupies an entire block. The historic structure is fronted by Bullion Street; Jones Street is to the rear, with 9th and 10th Streets on either side. This handsome, white judicial building erected with whip-sawed wood from nearby forests is the oldest courthouse still in use in California: cases are still tried there to this day. The courthouse is so recognizable that its likeness is on the Mariposa County Seal. Also particularly noteworthy is the courthouse's clock tower and bell, which chimes every hour, on the hour, 24 hours a day, 7 days a week. The county took its name from
