Today, relics of early manorial life in the early United States are found in a few places such as the Eastern Shore of Maryland with examples such as Wye Hall and Hope House (Easton, Maryland), Virginia at Monticello and Westover Plantation, the Hudson River Valley of New York at Clermont State Historic Site or along the Mississippi such as Lansdowne (Natchez, Mississippi). Over time, these large estates were usually subdivided as they became economically unsustainable and are now a fraction of their historical extent. In the southern states, the demise of plantation slavery after the Civil War gave rise to a sharecropping agricultural economy that had similarities to European serfdom and lasted into the early 20th century. The Biltmore Estate in North Carolina (which is still owned by descendants of the original builder, a member of the Vanderbilt family) is a more modern, though unsuccessful, attempt at building a small manorial society near Asheville, North Carolina.
