The Convent of the Sacred Heart, the oldest independent all-girls school in Manhattan, is a member of the Society of the Sacred Heart schools, a Roman Catholic institution founded in 1881. Since 1934, Sacred Heart School has occupied two adjacent mansions on East 91st Street which face Andrew Carnegie's 1902 mansion across the street (now the Cooper-Hewitt, National Design Museum of the Smithsonian Institution).

Burden Mansion
 
The largest mansion, at 1 East 91st Street on the northeast corner of Fifth Avenue, was built in 1917 for Otto Kahn (1867-1934), who was an investment banker, collector, philanthropist and lavish patron of the arts, most notably of the Metropolitan Opera. Kahn's 80-room Italian Renaissance-palazzo style mansion, designed by J. Armstrong Stenhouse and C. P. H. Gilbert, was modeled after the Cancelleria in Rome. Completed in 1918, the mansion served as Kahn's New York City residence until his death in 1934 at age 67. Shortly thereafter, Kahn's wife, Addie, sold the house to the Convent of the Sacred Heart, which uses it for its Middle and Upper schools. In 1970 the house was designated a landmark by the New York City Landmarks Preservation Committee.

Directly to the east at 7 East 91st Street is the former James A. and Florence Vanderbilt Sloan Burden mansion, an Italian Renaissance-style townhouse designed in 1902 by Warrren, Wetmore & Morgan. The Burden mansion now houses the Duchene Residence School (Lower School) of the Convent of the Sacred Heart. In 1974 the Burden mansion was designated by The New York City Landmarks Preservation Commission, which described the Burden mansion as having “the finest Beaux Art townhouse rooms in the City.”
