Why it's listed
Sunnyside is the Hudson River home of author Washington Irving, on Route 9 near Tarrytown, New York. The core of the house is a small 17th-century Dutch stone cottage, traditionally dated 1656. Irving first saw it as a youth and bought it in 1835, after returning from 17 years in Europe. Working with Boston artist George Harvey, he enlarged it with a stone ell, red tile roofs, crow-stepped gables, a Gothic-style porch and, in 1847, a stuccoed three-story tower mixing Gothic and Chinese-inspired details. He also laid out winding paths, gardens, an orchard and ponds across the grounds. Irving lived and worked here until his death in 1859. The Irving family kept the property until John D. Rockefeller bought it in 1945, and Sleepy Hollow Restorations now operates it as a museum. A 1896 wing was removed during restoration in 1959-60, and the kitchen yard was reconstructed. About 27 acres of the original estate lie within the landmark boundary.
Significance in brief: The property was the home where Washington Irving lived and worked for the last 24 years of his life, after returning from Europe as America's foremost prose writer. The house was remodeled to Irving's own picturesque taste with George Harvey, and the grounds were landscaped by Irving. It is maintained as a memorial to him.
