The first courthouse in Denton was a two-story frame structure on the north side of the downtown square. The building burned in 1875, destroying most of the county records. A brick courthouse was then built in the center of the square, a two-story building with a tall central tower. Lightning damaged that building and it was condemned and demolished in 1894. Construction of the present Courthouse-on-the-Square began in 1895. The cornerstone was laid in 1896, and the courthouse was dedicated in 1897.
