Built in 1822 by William Winfree, Magnolia Grange is a Federal-style house named for the large stand of magnolia trees in the front yard. It was originally surrounded by a 600-acre farm. A nearby tavern provided lodging for persons with business at the Courthouse, and a grist mill formerly stood on nearby Cold Water Run. From 1881 to 1969 it was the residence of the Cogbill family, whose members figured prominently in the political history of Chesterfield County.
