Today, nearly 33,000 buildings throughout the city are protected as individual landmarks, interior landmarks, or as part of 114 historic districts 

 

Such a success might have been difficult to predict after the wrecking ball demolished the city’s beloved Pennsylvania Station in 1963.  However, that act galvanized the growing preservation movement which led to the signing of the New York City Landmarks Law by Mayor Robert F. Wagner, Jr. on April 19, 1965. Fifty years later, New York City's Landmarks Law is a model for communities around the world.
