The most recent archaeological work on site was the result of finds discovered during restoration of the elliptical drive north of the Cottage and rehabilitation of the landscape immediately north of the front entrance to the Cottage.
Restoration of the ellipse included removal of the asphalt covering the elliptical driveway and the concrete curb north of President Lincoln’s Cottage. During the removal process, three architectural features were uncovered: a brick drain to the south of the ellipse and a brick walkway and a cobblestone gutter on the east side of the driveway.
