About the Park

Weeks State Park and the John Wingate Weeks Historic Site is the former Mount Prospect estate built at the direction of John Wingate Weeks, U.S. congressman, U.S. senator, and Secretary of War under Presidents Harding and Coolidge. The 338 +/- acre Mount Prospect estate was given to the state of New Hampshire in 1941 by John W. Weeks' children, Katherine Weeks Davidge and Sinclair Weeks. Set at the very top of Mount Prospect in Lancaster, New Hampshire, the house and grounds provide a 360-degree panorama of mountain splendor, including the Presidential Range of the White Mountains, the Green Mountains of Vermont, the Kilkenny Range, the Percy Peaks, and the upper Connecticut River Valley. Visitors can climb the old stone fire tower for even better mountain views. The John Wingate Weeks House Museum is also open to the public and tours are offered during the operating season. The summit and house museum can be accessed by The Mountain Road, a 1.6 mile scenic byway and auto road, which is open seasonally. The road and trails can be hiked any time of the year.

We are very grateful to the U.S.S. John W. Weeks DD-701 Association, as they have been very supportive and helpful in creating a special exhibit at the historic site museum. Many of the artifacts on display have been donated by the men who served on the naval destroyer. To learn more about this exhibit and the U.S.S. John W.
