John Wingate Weeks Historic Site

The 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. 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. 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.

While the park facilities are closed for the season, the park lands are always open for recreation.

New for 2008: All New Hampshire residents are admitted free of charge.
Other admission is $7 for adults; $3 for children ages 6-11; children ages 5 and under are admitted free.


The Weeks State Park Association hosts a series of weekly summer programs related to the north country of New Hampshire. The programs, which are free and open to the public, are held Thursday evenings. Check back for the 2009 summer schedule.
