William E. Ward House
William E. Ward House, Gothic Revival residence in Rye Brook, United States.
The William E. Ward House features a two-story main structure with a mansard roof and a four-story crenellated tower overlooking the Byram River.
Built between 1873 and 1876, this residence stands as the first reinforced concrete building in the United States, using 4,000 barrels of Portland cement.
Local residents initially called the building Ward's Folly due to its experimental construction method, later changing their perception to Ward's Castle.
The property spans 8 acres across the New York-Connecticut border, with the majority of the land situated in Connecticut near NY 120A.
William E. Ward tested the building's structural integrity by loading 26 tons of weight on the floor, which deflected only one hundredth of an inch.
