Union County Courthouse, Victorian courthouse in Monroe, United States

Union County Courthouse in Monroe is a Late Victorian building: a two-story, five-bay main block flanked by a two-bay wing on each side, with a low hip roof topped by a large cupola. Two three-bay wings were added in 1922. It was listed on the National Register of Historic Places in 1971 and stands within the Monroe Downtown Historic District.

The courthouse was initially erected in 1886 and received its expanded wings in 1922, reflecting its growth as an important administrative center. These construction phases occurred after Union County itself was established and demonstrate the development of local government over several decades.

The courthouse stands within the Monroe Downtown Historic District, a commercial core of late 19th- and early 20th-century storefronts around the 1886 building. Its 1971 listing on the National Register of Historic Places recognised the Late Victorian design with its low hip roof and large cupola. The building remains the seat of Union County government and courts in Monroe.

The courthouse stands in the Monroe Downtown Historic District, so the surrounding blocks can be covered on foot. The 1886 block faces the street with its cupola visible from a distance; the 1922 wings extend to either side. Court is in session on weekdays, so keep to public areas and avoid photographing proceedings.

The 1886 courthouse was enlarged in 1922 with two three-bay wings, and the whole building was listed on the National Register of Historic Places in 1971. It also stands within the Monroe Downtown Historic District, so the courthouse can be seen as part of a wider group of protected downtown buildings.
