Old Mahoning County Courthouse

Why it's listed
Built in 1848 on the village green in Canfield, this two-story brick building served as the first Mahoning County courthouse. It follows the Greek Revival temple form, with flat engaged pilasters running around every side, a fine Doric frieze and cornice details of mutules and guttae. An octagonal cupola once crowned the roof and was still in place in 1907. The courthouse went up soon after the county was created in 1846, funded by a $10,000 subscription. Canfield lost the county seat to Youngstown in 1876, and the property reverted to Judge Newton, the original owner. He donated it to the North Eastern Ohio Normal College, which added a west wing in 1881-1882 with a blind arcade facade. The building later housed a high school and grade school until 1919. Interiors were remodeled for offices, but the brick exterior was cleaned of white paint in 1972, and cupola reconstruction was underway.
Significance in brief: The nomination argues it is significant because it was built when Mahoning County was created and Canfield became county seat. It is also a major, fully developed masonry example of Greek Revival architecture. Later it served as a normal college and school.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
