The William E. Ward House, known locally as Ward's Castle, stands on Magnolia Drive along the New York–Connecticut border in the Rye Brook and Greenwich area. Built in the 1870s by mechanical engineer William E. Ward and his collaborator Robert Mook, this pioneering structure is the first reinforced concrete building in the United States, constructed to demonstrate the material's viability for architecture. Its design combines Second Empire and Gothic Revival elements, employing reinforced concrete throughout. The house later became notable as the home of the Museum of Cartoon Art from 1976 to 1992, after cartoonist Mort Walker, creator of *Beetle Bailey*, purchased the property. It is recognized as both a Historic Civil Engineering Landmark and a listed place on the National Register of Historic Places.
