Marsh-Billings-Rockefeller National Historical Park is a United States National Historical Park in Woodstock, Vermont. The park preserves the site where Frederick Billings established a managed forest and a progressive dairy farm. The name honors Billings and the other owners of the property: George Perkins Marsh, Mary Montagu Billings French, Laurance Rockefeller, and Mary French Rockefeller. The Rockefellers transferred the property to the federal government in 1992. It is the only unit of the United States National Park System in Vermont (except for a portion of the Appalachian Trail).Features and facilitiesMarsh-Billings-Rockefeller National Historical Park is located just northwest of Woodstock village, on the west side of Vermont Route 12. Opposite it on the east side of the road stands the Billings Farm, a working farm and heritage museum also on land originally belonging to the Billingses. Parking for both properties is located on the east side of VT 12, and National Park Service staff attend visitors at both the farm's visitor center, and one located on the park property. The area nearest the road is a landscaped area featuring the George Perkins Marsh Boyhood Home, the architectural centerpiece of the park and a National Historic Landmark. Although it was built in 1805, it underwent major alterations under Frederick Billings to achieve its present Late Victorian splendor. Visitors can take guided tours of the house (reservations recommended due to limited availability), which include displays of landscape paintings, highlighting the influence painting and photography had on the conservation movement. The gardens have also been restored.
