The site of the first settlement, Fort Germanna, is located in present-day Orange County along the banks of the Rapidan River, with subsequent settlements of Germans being established on sites in present-day Culpeper and Spotsylvania counties. Many Germanna families played roles in important events in early American history such as the American Revolution and migration west to Kentucky and beyond. The site of Fort Germanna is mostly open fields with intervening thickets of second-growth timber. The Fort Germanna site was listed on the National Register of Historic Places in 1978. Traces of the terraces of Spotswood's mansion which came to be known as the "Enchanted Castle" are still discernible. The Germanna Foundation is conducting archaeological exploration of the Fort Germanna, Siegen Forest, and Salubria sites that it owns in Orange and Culpeper Counties. The Germanna Foundation owns land on the original Germanna peninsula, on both sides of the Germanna Highway, State Route 3, near the site of the original Fort Germanna, once the westernmost outpost of colonial Virginia. The Germanna Foundation operates the Brawdus Martin Fort Germanna Visitor Center on the Siegen Forest side of the Germanna Highway, east of Culpeper and west of Fredericksburg, Virginia. The Foundation also owns a nearby 18th century mansion, Salubria, once the home of Governor Spotswood's widow. In October 2000, Salubria was donated by the Grayson family to the Germanna Foundation for historic preservation. The Foundation maintains a research library, a memorial garden, and plans interpretive walking trails to various historic and archaeological sites. In addition, the Foundation publishes histories and genealogical books, a newsletter, offers educational programs at an Annual Historical Conference and Reunion and to the community, and offers group travel to Germany geared to the origin of the Germanna families. The first colony consisted of the family surnames: Albrecht, Brombach, Fischbach/Fishback, Friesenhagen, Hager, Heide/Heite/Hitt, Heimbach, Hoffman, Holtzklau/Holtzclaw, Huttman, Kemper/Camper, Cuntze/Koontz, Merdten/Martin, Otterbach/Utterback, Reinschmidt, Richter/Rector, Spielmann, Weber/Weaver
