Old Governor's Mansion
Also known as: Executive Mansion
Why it's listed
Completed in 1838 in Milledgeville, this brick and stucco mansion was the first building in Georgia designed specifically as the governor's residence. The Legislature authorized it in 1835, and Charles B. Cluskey's plan was chosen over John Pell's because it promised lower cost. Timothy Porter oversaw construction, which ran to about $50,000. A prostyle Ionic portico fronts the house, and inside a central rotunda with a coffered plaster dome organizes rooms of octagonal, round and square shapes. Governors lived here from 1839 to 1868. General William T. Sherman made his headquarters in the house in November 1864, and Governor Joseph E. Brown was arrested there in May 1865. After use as a boarding house and cadet dormitory, it became a dormitory and president's home for Georgia Normal and Industrial College. A 1960s restoration removed a Gothic-style cupola, and the ground and first floors have been open for tours since 1967.
Significance in brief: The nomination presents it as an outstanding Greek Revival house by architect Charles B. Cluskey, with a sophisticated plan of varied room shapes around a central rotunda. It also served as the residence of Georgia governors from 1839 to 1868 and was tied to Civil War and Reconstruction events. It later became a college dormitory and president's home, and it is claimed to have local, state and national significance.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
