Courthouse Campus History The Dickinson County Courthouse and Jail, designed by former Iron Mountain resident J. E. Clancy, occupy a square block bounded by Washington Avenue, Stephenson Avenue, and “C” Street in a downtown commercial district of Iron Mountain. The courthouse, erected in 1896-1897, stands near the center of the block facing south on “C” Street. The jail, also erected in 1896-97, stands on the southeast corner of the campus. The Dickinson County Courthouse clock was the last weight and pulley tower clock in the State of Michigan. The clock in the 89-foot courthouse tower was made by the Seth Thomas Clock Company in 1935. The clock was converted from the original weight and pulley system to electrical operation in the mid-1950s. The campus was applied to be listed in 1980 with the National Register of Historic Places when Daniel M Lori was County Chairman.
