The county was established in 1851. In 1855 a county government was set up in
the town Carrollton. Three years later a courthouse was constructed at a cost of
approximately $3,000. Construction was begun by Nelson Moore, but he died with
only one floor completed. The second story was completed by L. J. Hampton.
In 1869 the centrally located railroad town of Carroll City was selected as the
county seat, replacing, with some protest, Carrollton. The Chicago and
Northwestern Railroad laid out the town and built its first building, a
warehouse. Later a $4,000 courthouse was constructed on the town square. This
building was used until it burned to the ground in 1886. The vaults and records
were undamaged, however, and moved to temporary housing in the Joyce Building
and Drees' Music Hall.
The following winter a $40,000 bond issue was approved toward the construction
of a new, permanent courthouse. The impressive building was built on the
northwest corner of the square (the parking lot of the current courthouse). The
stone and brick building, complete with a clock tower, was used for more than
three-quarters of a century. It was replaced by a modern-looking building in
1965.
A $750,000 bond issue was used to construct and equip the new courthouse. This
building was officially dedicated on September 24, 1966. The highlight of the
dedication ceremony was the opening of the boxes sealed in the cornerstone of
the old courthouse. The bell from the previous courthouse clock tower sits on
the courthouse grounds.
