Language of Landmarks
In 1965, the Landmarks Law was signed by Mayor Wagner and empowered the New York City Landmarks Preservation Commission (LPC) to designate and regulate historic districts and individual landmarks.
Historic District: An area of the city designated by the LPC to safeguard the special character or “sense of place” that results from the area’s architectural, historical, or cultural significance.
Individual (Exterior) Landmark: A structure at least 30 years old with architectural, historical, or cultural value that is designated by the LPC to protect its significant exterior features.
Individual (Interior) Landmark: An extraordinary interior space designated by the LPC to secure architectural features, fixtures and spatial characteristics that might be lost in future renovations or alterations. To qualify, interiors must be at least 30 years old, generally open to the public, and not used for religious purposes.
Scenic Landmark: City-owned landscapes, either natural or man-made, which the
LPC protects by designation to maintain their contribution to the shape of the city and to the quality of life within it.
