Things to See & Do in Sleepy Hollow
Old Croton Aqueduct Historic State Park: The Croton aqueduct is a linear park above the old aqueduct that supplies water to NYC. It is a lovely trail for hikers and bikers that runs the length of the river towns and weaves past some of the sites you will tour. It also has great views of the river.
Lipshitz studio - Lipshitz was a sculptor who moved his studio to Hastings in 1963. The cool, curved concrete studio designed by the architect Lowenfish was shuttered after Lipshitz's death and in the last few years was donated by the Lipshitz family to the village. It's an amazing building on the aqueduct.
The Keepers House: During the operational years of the Old Croton Aqueduct, overseers responsible for maintaining specific sections of this crucial water system were provided with housing near their assigned stretches of the tunnel. The only such residence that remains in its original location is the brick Italianate-style Keeper’s House, located along the trail at Walnut Street in Dobbs Ferry. Built in 1857, it served as the home of James Bremner, the principal superintendent of the Aqueduct north of New York City. Today, the Keeper’s House is a notable feature of the Aqueduct Trail, which was designated a National Historic Landmark in 1992.
Draper Observatory cottage - This National Historic Landmark, perched near the summit of the Palisades in Hastings-on-Hudson, was once used by pioneering astronomer Henry Draper in the mid-19th century. Built as part of his private observatory complex, the cottage played a key role in some of the earliest astrophotography experiments.
Ever Rest - In the mid-1830s, local industrialist William Saunders built a Carpenter Gothic–style home on two acres at 49 Washington Avenue. In 1885, renowned painter Jasper Cropsey and his wife Maria moved to Hastings-on-Hudson and purchased Saunders’ former residence the following year. Jasper named the house “Ever Rest,” likely reflecting his vision of the property as a serene and peaceful retreat where he and Maria could spend their later years together.
Lord and Burnham building - The Lord & Burnham Building, a brick structure at the corner of Main and Astor Streets in Irvington, was built in the 1880s in the Queen Anne architectural style. It was added to the National Register of Historic Places in 1999 and designated a contributing property within the Irvington Historic District in 2014.
C.J. Walker estate: Villa Lewaro, located in Irvington, New York, is the historic home of Madam C. J. Walker, America’s first self-made female millionaire. Born Sarah Breedlove in 1867 to formerly enslaved parents, Walker overcame immense racial and social barriers to become a symbol of entrepreneurial success. Villa Lewaro became a gathering place for Harlem Renaissance luminaries like W.E.B. Du Bois, Langston Hughes, and Zora Neale Hurston. Set on over three acres of sloping landscape, the estate includes a music salon, an original Estey organ, and well-preserved interiors. Designated a National Historic Landmark in 1976, Villa Lewaro stands today as a powerful reminder of Walker’s extraordinary life and legacy.
The Union Church of Pocantico Hills: Stained-glass windows by European masters, commissioned by the Rockefeller family, adorn this unassuming country church. Henri Matisse’s last commissioned work, the Rose Window, and nine windows by Marc Chagall create a dramatic combination of light and color, art and spirituality. Step inside and be inspired.
The Armour-Stiner Octagon House in Irvington is a one-of-a-kind domed, eight-sided home built in the 1860s. Inspired by a popular architectural trend of the time, it was later transformed by tea merchant Joseph Stiner into a grand summer retreat resembling a classical Roman temple.
