Boone County Courthouse (Illinois)

The two principal Boone County governmental buildings in use today were originally built in 1854−1855 (Courthouse) and 2008−2009 (County Administration Building). The Italianate Courthouse, built in the 1850s for $9,000 in the gold-coin money of the day, could house the entire administrative, office, and judicial functions of the county. A neo-Italianate annex was built in 1878 to house the Clerk's office, and a modern structure was built in 1958 to add courthouse footage and join the two older buildings. Further judicial-space renovations took place in 2009.^[3]

A County Administration Building, also located in Belvidere but physically separate from the Courthouse on the opposite side of the Kishwaukee River, was built in 2008−2009 as 1212 Logan Avenue. The Administration Building houses the administrative offices of Boone County government.^[3]

Prior to the construction of the oldest section of the current Courthouse in 1854−1855, Boone County used a temporary brick structure (built in 1840−1843) until 1853.^[3]
