Replacement Jail
That same year, a replacement jail was constructed from 24 inch thick granite blocks quarried at Mormon Bar. This building still stands on Bullion Street. The new jail cost the county almost $15,000, and was originally a two story structure with a flat roof and a gallows built on and extending from the east end of the building.
In 1892 the building was gutted by fire, possibly set in an escape attempt, which took the life of the sole inmate. The jail was then rebuilt with the gable roof now seen on the building. This facility remained the Mariposa County jail until it was condemned in 1963.
Incorporation
At that time the jail facility was incorporated at the current site of the Mariposa County Sheriffs Department, where it was slowly enlarged over time to meet the increasing need. The facility remained there until 1995. In that year, the Sheriff’s Department Dispatch organization took over the facility, and in March of that year the current jail was opened on Highway 49 North, approximately one mile north of the town of Mariposa.
Today
Today the Mariposa County Adult Detention Facility, located at 5379 Highway 49 North, is a modern full function facility with a capacity of about 60 inmates.
