How was the landscape partitioned?. . About 200 feet north of this location, a fence marked the edge of the "curtilage." This sixty-one acre area separated the house and designed landscape from the larger plantation. In 1813, Jefferson noted that he had "inclosed and divided it into suitable appendages to a Dwelling house," and had begun its "improvement by planting trees of use and ornament." , , (left image text) , Four roads linked the main house with the outside world. Internal roads, such as the one that encircled the house and core landscape, carried people and goods within the plantation. , (center image text) , A portion of the curtilage fence has been recreated along the front entrance drive. This traditional "Virginia" or "snake" fence is built of hand-split Black Locust rails stacked loosely in a zig-zag pattern. As in Jefferson's day, the bottom rails rest on fieldstones to prevent rotting from contact with the ground. , (right-top image text) , Archaeologists discovered a series of planting holes that likely define the inner and outer edges of a segment of Jefferson's circular road. He described the road as 540 yards in circumference. , (right-bottom image text) , The pattern of planting holes is nearly identical to Jefferson's plan to line both sides of the road with Paper Mulberry trees planted 20 feet apart.
