In 1965, in the wake of the destruction of Penn Station and with Grand Central Terminal threatened, Mayor Robert F. Wagner signed New York City’s groundbreaking Landmarks Law, the first legislation of its kind in the country intended to protect and preserve historically significant buildings. In 1973, with the owners of Grand Central still eager to gut the building’s beloved interior, a set of amendments to the original law granted the Landmarks Preservation Commission the authority to designate interior spaces as historic landmarks as well.

Over the course of 2015, well over a hundred arts, cultural, and civic organizations have joined the NYC Landmarks50 Alliance to organize an incredible array of public programs, ranging from exhibitions and festivals to walking tours and lectures, in celebration of the Landmarks Law’s 50th anniversary.

What qualifies an interior as a historic landmark? Like all landmarks, an interior must be at least thirty years old and have significant historic or aesthetic interest or value. In the cases of interiors, they must also be “customarily open or accessible to the public, or to which the public is customarily invited,” and the designation applies to the “architectural style, design, general arrangement and components,” but does not include movable furnishings.
