The Church of the Heavenly Rest is an Episcopal church located on the corner of Fifth Avenue and 90th Street, opposite Central Park and the Carnegie Mansion, on the Upper East Side of New York City. The church is noted for the architecture of its building, its location on Museum Mile, its outreach, thrift, music and arts programs, and some of its congregation members.

The Andrew Carnegie Mansion is a historic house and a museum building at 2 East 91st Street, along the east side of Fifth Avenue, on the Upper East Side of Manhattan in New York City. The three-and-a-half story, brick and stone mansion was designed by Babb, Cook & Willard in the Georgian Revival style. Completed in 1902 for the industrialist Andrew Carnegie, his wife Louise, and their only child Margaret, it served as the family's residence until 1946. Since 1976, the house has been occupied by the Cooper-Hewitt Museum, part of the Smithsonian Institution. The mansion is internally connected to two townhouses at 9 East 90th Street and 11 East 90th Street, both of which are part of the Cooper-Hewitt.
