A New York City Landmark is a building, structure, or site that has been designated as having historical, cultural, or architectural significance. These landmarks are protected by the city to preserve their unique character and history. Examples include the Statue of Liberty, Empire State Building, and Brooklyn Bridge. The New York City Landmarks Preservation Commission is responsible for identifying and designating these landmarks. Once a site is designated, any alterations or demolitions require special approval to ensure the landmark's integrity is maintained. This helps to celebrate and protect the rich history of New York City.
