In 1903, Andrew Carnegie decided to build a home that would redefine the Upper East Side. His mansion at 2 East 91st Street wasn't just a display of wealth; it was a feat of early engineering. It was the first house in New York to feature both a steel frame and central heating.
Before Carnegie arrived, this area was semi-rural, part of the city's old Common Lands. The mansion's arrival accelerated the development of the neighborhood, which we now know as Carnegie Hill. Designed by Babb, Cook and Willard, the estate became the anchor of a district defined by Neo-Georgian and Beaux-Arts styles.
Today, the mansion is a National Historic Landmark, marking the spot where industrial success met architectural innovation.
