Landmarks45.org is dedicated to celebrating the forty-fifth anniversary of New York City's landmarks law. This site is a project of the New York Preservation Archive Project.

On April 19, 1965, Mayor Robert Wagner signed New York City’s Landmarks Law, and a new era in historic preservation began. This anniversary provides the preservation community with an opportunity to reflect upon our past and prepare for the future. With your help, we can document the landmark accomplishments of the past forty-five years, and prepare for the work to come.
