Why it's listed
Built in the 1870s as the Robertson County Courthouse in Calvert, Texas, this two-story Gothic Revival building of dark red brick is laid out roughly as a Latin cross. Crenellated parapets, brick buttresses, cast iron hood molds and a three-part bay window mark its exterior. A smaller two-story brick structure at the rear, once the jail, connects to it by a wooden bridge, and a handsome carriage house with large arched openings stands to the northeast. Plans for the courthouse were accepted in 1875, with W.T. Ingraham of St. Louis as architect. Calvert was left with an unneeded building when the county seat moved to Franklin. In 1885 merchant and banker Robert A. Brown bought it and converted it into a home. The Hammond family acquired it in 1909 and held it until 1966, when it passed to the county historical society, which planned a museum. The property reflects both Gothic Revival design and the changing fortunes of Robertson County.
Significance in brief: The nomination presents it as an elegant example of Gothic Revival architecture, with crenellated parapets, buttresses, cast iron hood molds and a front bay window. It also reflects Robertson County's history: it was built as the courthouse, then became a private home after the county seat moved to Franklin, and is now slated to become a museum.

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.
