Is the Empire State Building a National Monument?

No. The Empire State Building is not a national monument. It is a privately owned, 102-story Art Deco skyscraper in Midtown Manhattan, New York City.

Designations It Does Hold

• National Historic Landmark (1986) – Highest federal recognition for historic properties; acknowledges architectural and cultural significance.
• New York City Landmark (1981) – Exterior and lobby interior protected by NYC Landmarks Preservation Commission.
• National Register of Historic Places (1982).
• ASCE Historic Civil Engineering Landmark (2005).

National Monument vs. National Historic Landmark

• National Monument: Created by presidential proclamation (Antiquities Act) or Congress; federally owned/managed (NPS, BLM, USFS, etc.); usually natural, archaeological, or historic sites (e.g., Statue of Liberty, Devils Tower).
• National Historic Landmark: Honorific designation for buildings, districts, objects, sites of exceptional significance; ownership unchanged; no federal management authority.

The Empire State Building remains an iconic office tower and tourist attraction—its observation decks draw 4M+ visitors yearly—but it is not, and never has been, a national monument.
