Impact

As the tallest building in the world and the first one to exceed 100 floors, the Empire State Building immediately became an icon of the city and of the nation. In 2013, Time magazine noted that the Empire State Building "seems to completely embody the city it has become synonymous with". The historian John Tauranac called it "'the' twentieth-century New York building", despite the existence of taller and more modernist buildings.

The New York City Landmarks Preservation Commission voted to designate the building and its lobby as city landmarks on May 19, 1981, citing the historic nature of the first and second floors, as well as "the fixtures and interior components" of the upper floors. The New York City Planning Commission endorsed the landmark status. The building became a National Historic Landmark in 1986 in close alignment with the New York City Landmarks report. The Empire State Building was added to the National Register of Historic Places the following year due to its architectural significance.
