The current Worth County Courthouse was completed in 1893, across the street from the modest two-story brick courthouse that was constructed 13 years earlier and still open as a museum today. The courthouse was remodeled and expanded to the east in 1938 with funds as part of the Works Progress Administration, and in 1990, a one-story addition containing a new jail, courtroom and offices was attached to the northwest portion of the facility. The historic courthouse was added to the National Register of Historic Places in 1981.
