Background
The Dubuque County Jail is a historic building at 36 East 8th Street in Dubuque, Iowa, United States. Completed in 1858, the jail is an example of the uncommon Egyptian Revival style. It is architecturally a highly original work of John F. Rague, who also designed the 1837 Old Capitol of Illinois and the 1840 Territorial Capitol of Iowa. The building was designated a National Historic Landmark for its architecture in 1987. It served as a jail for more than a century, became a museum in 1975, and was converted into county offices in 2016.
