This was one of four mansions I toured today. I am glad I included this one, but if you only have time to see one antebellum mansion, it should not be this one. The draw of Longwood is really its story, rather than its execution. The owner picked an cutting-edge, 6-story octagonal design from the book of a Philadelphia architect. The entire structure was completed in a year, but only the basement level interiors were finished. The Civil War intervened and the family continued to dwell in the basement with five unfinished stories above them. The exterior, meant to have been stuccoed and scored in imitation of stone, remains brick. It claims to be the largest octagonal building in the United States. The furnishings are not glamorous if that is what you wish to see. In sum it is a very sad place, with a sad place in history.
