Knollwood is a once-in-a-century opportunity to own one of America's most storied private estates-a living chapter of American history and a destination associated with influence and culture. Built in 1900 by Franklin MacVeagh, U.S. Secretary of the Treasury, and later acquired by Ernest Henderson, founder of Sheraton Hotels, Knollwood has had only two owners in its 124-year history. From 1910 to 1913, President William Howard Taft used it as his occasional Summer White House, hosting summits and gatherings that helped shape the nation. In the same era, Mark Twain spent weeks here reading Huckleberry Finn to guests in its grand rooms. Listed on the U.S. National Register of Historic Places and perched atop a ridge of Mount Monadnock, the estate commands sweeping 40-mile views across 100+ acres of gardens, forests, and a boutique vineyard. The 14,500+ sqft Georgian-style residence offers 13 bedrooms, 9.5 baths, a 26-seat dining room, library, terraces, and a grand ballroom seating 120. Additional structures include a heated 3-car garage with apartment above and a historic 3-stall barn. Purpose-built for grand entertaining, luxury retreats and boutique hospitality ventures (weddings, bed and breakfast lodging etc). less than 2 hours from Boston and ~20 minutes from Keene Dillant-Hopkins Airport, Knollwood offers a rare blend of privacy and accessibility in tax-free, business-friendly New Hampshire, surrounded by 4-season recreation-skiing, hiking, fishing, golfing, kayaking, horseback riding, and more.
