New York City has been in a constant state of construction since the very beginning. Throughout its history, the city has evolved into an architectural destination. With the 400th anniversary of the city’s founding right around the corner, it’s the perfect time to explore the buildings that make up the Big Apple’s iconic skyline, as well as the lesser known structures you won’t find in guidebooks. In the forthcoming new book A History of New York in 27 Buildings (Bloomsbury, October 22), New York Times correspondent Sam Roberts tells the stories of the city’s most important architectural works and the people who made them possible.
