Founded in 1951 as Sleepy Hollow Restorations by John D. Rockefeller, Jr., Historic Hudson Valley is a 501(c)(3) organization chartered by the New York State Department of Education and the largest non-profit cultural organization in Westchester County. We educate and entertain hundreds of thousands of visitors a year through school programs, tours of five National Historic Landmarks, and large-scale events like The Great Jack O’Lantern Blaze. From its lower Hudson Valley base of operations, the organization focuses on delivering quality educational and entertaining experiences, striking a balance between tradition and vision, from preserving the past, to contextualizing it for 21st-century audiences.
