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.","narrative":"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.","period_of_significance":"1880-1885; late 1870's","architect_builder":"W.T.
