Kearney.","why_significant":"It is significant under Criterion A for its association with the development of women's education in New York City, through a progressive girls' boarding school run by the Society of the Holy Child Jesus. It is significant under Criterion C as a finely crafted example of modified Collegiate Gothic architecture, notable for load-bearing walls of local Manhattan schist and fire-resistant construction.","narrative":"Overlooking the Hudson River from Riverside Drive in Hamilton Heights, this former girls' boarding school was built between 1911 and 1913 to designs by John W. Kearney. The Sisters of the Holy Child Jesus founded the academy in 1904 and followed Mother Cornelia Connelly's progressive curriculum, which included science, fine arts, drama, music and physical education for girls. The building is a modified Collegiate Gothic design with a five-story tower, crenellated parapets, gabled wall dormers and cast stone trim. Its load-bearing walls of dark Manhattan schist, likely quarried during subway construction, set it apart from many veneer-clad examples of the style. Steel columns, concrete floors and protected stairwells reflect early twentieth-century concern for fire safety. The school left in 1957, and later uses included a yeshiva until 1975. After years of vacancy, a rehabilitation that began in 1998 converted the building to housing and services for ex-offenders, and it received a 2002 preservation award.","period_of_significance":"1911-1913","architect_builder":"John W.
