Knollwood is a once-in-a-century opportunity to own one of America’s most storied private estates—a living chapter of U.S. history. Built in 1900 by Franklin MacVeagh, U.S. Secretary of the Treasury, & later acquired by Ernest Henderson, founder of Sheraton Hotels, Knollwood has had only 2 owners in its 124-year history. From 1910 to 1913, President William Howard Taft occasionally used it as his Summer White House, hosting political summits & gatherings that shaped the nation. In the same era, Mark Twain spent weeks here, reading Huckleberry Finn to guests in its grand rooms. Over the decades, nearly every major political figure has walked its halls, cementing its status as a destination for power, influence, & culture. Listed on the U.S. National Register of Historic Places & perched atop a ridge of Mount Monadnock, the estate commands sweeping 40-mile views over 100 acres of gardens, forests, & a boutique vineyard. The Georgian-style, residence offers 14,500+ sqft with 13 beds, 9.5 baths, a 26-seat dining room, library, terraces, & a grand ballroom seating 120. Additional structures include a 3-car garage with apartment above & a historic 3-stall barn. Purpose-built for grand entertaining & large-scale gatherings, Knollwood is ideally suited for luxury retreats, weddings & boutique hospitality. Nearby amenities include tennis, golf, swimming, hiking, horseback riding & snowshoeing, with the Keene Dillant-Hopkins Airport—accommodating private jets—13 miles away.
