The 18th-century plantation, now owned by the Lafferty family, has been in continuous operation for more than 300 years. In addition to the plantation house, dependency buildings and cultivated land, Elsing Green includes 2,454 acres (993 ha) of surrounding farmland, forest and marsh land. Elsing Green has been on the Virginia Landmarks Register and the National Register of Historic Places since 1969, and received formal National Historic Landmark status in 1971.
