Features such as the Stone Bridge, Henry Hill, Chinn Ridge and the unfinished Manassas Gap Railroad grade are tied directly to the fighting. The form also records monuments dating from 1861 to 1940 and notes that modern additions do not contribute to its significance.","narrative":"Manassas National Battlefield Park covers 4,522 acres of gently rolling, half-forested land in Prince William and Fairfax counties, Virginia. It is the site of the First and Second Battles of Manassas, fought in 1861 and 1862. U.S. 29/211 and Va. 234 divide it into quadrants, following the lines of the wartime turnpike and Manassas-Sudley Road. Surviving features include the red sandstone Stone Bridge, the Stone House that served as a field hospital, Henry Hill, Chinn Ridge, and the unfinished railroad grade that sheltered Confederate troops in the second battle. Many wartime houses are gone and are marked by foundations or ruins, including Pittsylvania, Portici and the Chinn house. Monuments include two 1865 Union obelisks, the 1940 Jackson equestrian statue, and New York regimental memorials from 1906. The listing recognizes the battlefield landscape and these historic resources. Later buildings such as the visitor center do not contribute to its significance.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"The park is public and occupied, in good condition and altered, with some structures vacant or deteriorated.
