President Lincoln’s Cottage, Washington, D.C.
Throughout the peak years of the Civil War, Abraham Lincoln spent time off and on in what has become known as Lincoln's Cottage. Before opening it to the public, the National Trust for Historic Preservation spent years restoring the home to its appearance when Lincoln resided there. To be as respectful as possible of the historic building—and to avoid costly remodeling—the preservationists installed the Unico System, which operates quietly and stays out of sight.
