About this home

Knollwood is a once-in-a-century opportunity to own one of America’s most storied private estates—a living chapter of American history & a destination associated with influence & culture. 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 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 & 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 & perched atop a ridge of Mount Monadnock, the estate commands sweeping 40-mile views across 100+ acres of gardens, forests, & a boutique vineyard. The 14,500+ sqft Georgian-style residence offers 13 bedrooms, 9.5 baths, a 26-seat dining room, library, terraces, & a grand ballroom seating 120. Additional
