In 1758, the property goes to grandson. By 1797, Gordons own site of town and castle and build home one former Germanna tract. Little is known about the period of the Gordon ownership. During the American Civil War (1861-1865), the nearby Germanna Ford was used by Confederate and Union troops to manuever supplies and armies through. Civil War! By the 1920s, the old Gordon house and fields were abandoned.

    The 1933 David Bushnell survey for the Smithsonian Institution was conducted over land formerly a part of Spotswood's Germanna. Artifacts recovered were prehistoric in nature but due to the archaeological paradigm, or thought, at the time the artifacts were not dated or assigned any cultural context. The Enchanted Castle was discovered in 1960 but not excavated until 1969. Ned Heite, working for the Virginia Historic Landmarks Commission, found a large amount of brick rubble in association with 18th century artifacts. The site was listed on the Virginia Landmarks Register in 1976. The following year the Virginia Research Center for Archaeology (VRCA) carried out excavations there and the site was successfully incorporated into the National Register of Historic Places. Archaeological investigations in the 1980s continued to investigate the Enchanted Castle site.

    Today, the site has been abandoned by funds, research, and enthusiasm. It is under the ownership of the University of Mary Washington. The site's full excavation likely would reveal a great deal about the Manahoac tribe, enemies of the well researched and well known Powahatan's Confederacy, German immigrants to early colonial Virginia, the life of Alexander and Anne Spotswood at the Enchanted Castle. Further research could uncover the town, antebellum, the Civil War and post-Civil War activity at Germanna. Historians will continue to battle with those who put more energy into the myths surrounding the site and the people who lived on the site until the archaeology puts these mythological thoughts to rest.
