John Wingate Weeks Historic Site's Mt. Prospect estate was built at the direction of John Wingate Weeks, leading conservationist, U.S. congressman, U.S. senator, and Secretary of War under Presidents Harding and Coolidge. The 420-acre Mt. Prospect estate was given to the state of New Hampshire in 1941 by John Weeks' children, Katherine Weeks Davidge and Sinclair Weeks. Set at the very top of Mt. 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. Enjoy a historic Tower and the Lodge.
