Preservation & Sustainability


April 19, 2015 marks the 50th Anniversary of New York City’s groundbreaking Landmarks Law, the passage of which ushered in unprecedented historic preservation following years of advocacy by MAS.

It’s hard to remember today—with 1,347 individual landmarks, 117 interior landmarks, 114 historic districts, and 10 scenic landmarks across the five boroughs—that at the time of its passage, New York’s landmarks preservation law was a truly revolutionary concept. It would serve as a model for similar laws that were enacted around the country and forever change the way cities treat historic spaces.
