Today, Sotterley is the only tidewater plantation in Maryland open to the public that is a testament to all those that lived, died, labored, and resisted here. Designated a National Historic Landmark in 2000, Sotterley is older than Mount Vernon with a history that spans three centuries. A non-profit public charity, Sotterley is governed by a Board of Trustees that has included descendants of former owners and former enslaved, and is supported by fees, grants, memberships, sponsors, and events. The mission of Historic Sotterley, Inc. is to preserve our historic structures and natural environment and use the powerful stories of our land, lives and labor to bring American history to life while serving as a cultural resource. As part of the Southern Maryland community, Sotterley offers a variety of cultural and educational tours, events, exhibits, and programs for all ages on its beautiful 95 acre site on the shore of the Patuxent River.
