Celebrating 130 years of advocacy on behalf of New York and New Yorkers.


The Municipal Art Society Is Founded

The Municipal Art Society (MAS) is established on March 22, 1893, by Richard Morris Hunt and other civic activists, with a founding mission to beautify New York with public art. Throughout its first century, the organization expanded its mission to include the city’s buildings, streetscapes, and public spaces, with the aim of bringing the voice of the public into the debates that impact the lives of New Yorkers.

Calling for Isles of Safety

With automobile use on the rise, MAS convinces the City to create a pedestrian traffic island, a so-called isle of safety, at the dangerous intersection of Broadway, Fifth Avenue, and 23rd Street. In the following year, the City created several such isles of safety at various intersections along busy Broadway.

Identifying Future Landmarks

Between 1954 and 1957, before a mechanism existed for preserving historic properties, MAS surveyed buildings in all five boroughs to create a database of potential landmarks to preserve. Local residents and MAS staff compiled individual sheets devoted to about 200 buildings. Each sheet outlined the building’s date, location, and style and provided a description and small photograph.

Saving the Jefferson Market Courthouse from Demolition

MAS organizes a successful public campaign to save the Jefferson Market Courthouse, described by the AIA Guide to New York City as “a mock Neuschwansteinian assemblage … of leaded glass, steeply sloping roofs, gables, pinnacles, Venetian Gothic embellishments, and an intricate tower and clock; one of the City’s most remarkable buildings.” The campaign led to the Courthouse’s reuse as a branch of the New York Public Library.

Creating the First Historic District

MAS galvanizes Brooklyn Heights residents to campaign for their streets to be designated the first Historic District in New York City, establishing a new model for preserving not just individual buildings, but entire neighborhoods.

Passing the Landmarks Law

MAS helps win passage of New York City’s Landmarks Law, substantially broadening the powers of the Landmarks Preservation Commission. Today, the law serves as the model for preservation statutes in more than 500 municipalities across all fifty states.

Advocating for the South Street Seaport

MAS, the Friends of South Street, and the State Council on the Arts cosponsor an exhibition called “The Destruction of Lower Manhattan,” which focuses attention on threats to the historic neighborhood. The Landmarks Preservation Commission designates the South Street Seaport Historic District in 1977.

Saving the Tweed Courthouse from Demolition

MAS, the New York Landmarks Conservancy, and others successfully fought for the building’s survival when a task force under Mayor Beame recommended that the Tweed Courthouse be torn down and replaced with a City Hall annex. It has since been saved and fully restored and, since 2001, houses the City’s Department of Education.

Planning for the Second Avenue Subway

MAS partners with the City Planning Commission on a joint study of the planning implications for the proposed Second Avenue Subway and issues a set of permanent policy recommendations to achieve the new line.


Saving Grand Central Terminal from Demolition

With MAS Board Member Jacqueline Kennedy Onassis in the lead, the MAS formed the Committee to Save Grand Central Terminal in response to the Penn Central Railroad’s proposal to demolish the station. On April 16, 1978, more than 400 advocates traveled by train, dubbed the “Landmark Express,” to Washington D.C., in order to call attention to the Supreme Court hearing on the designation of the train station as a city historic landmark.

Producing “The Social Life of Small Urban Spaces”

In conjunction with William “Holly” Whyte, MAS establishes the Street Life Project in 1969 to observe and record how people use public space in the city. The most acclaimed result was The Social Life of Small Urban Spaces, a 1979 documentary that aired on PBS in 1980 and an accompanying book. Photo: Giles Ashford.

Protecting the Times Tower from Demolition

In partnership with the National Endowment for the Arts, MAS sponsors a competition in March for alternate ideas for the City’s proposal to demolish the Times Tower in favor of four anonymous office towers. More than 500 entries were contributed and the competition helped galvanize public opposition to the City-backed proposal. Photo: Wikimedia Commons, the Brown Brothers.

Saving the Lights of Times Square

MAS organizes the “Shut Off the Lights” protest in November, in which most illuminated signage in Times Square temporarily went dark with the exception of a message that read: “Hey, Mr. Mayor It’s Dark Out There: Help Keep Bright Lights In Times Square.” Two years later, the City updates the theater subdistrict zoning to require illuminated signage. Photo: Wikimedia Commons, Jean-Christophe Benoist.

Protecting the City & Suburban Homes

MAS submits the National Register nomination for the model tenements at the City & Suburban Homes York Avenue Estate. In 1990, the Board of Estimate modifies the Landmarks Preservation Commission’s designation, an action later overturned in court.

Standing Against the Shadow

More than 800 New Yorkers, including Jacqueline Kennedy Onassis and Bill Moyers, join MAS in Central Park and raise black umbrellas aloft to demonstrate the shadow that would be cast onto the park by a tower proposed for the Former Coliseum site on Columbus Circle. That project was modified to mitigate shadows effects in response to the public outcry. Thirty years later, our advocacy for light, air, and sound city planning continues through the Accidental Skyline project.

Protecting Public Art through Adopt-A-Monument

In response to the deterioration of many of New York City’s outdoor statues and public murals in hospitals, schools and libraries, and the limited resources to preserve them, MAS (in partnership with NYC Parks and the Public Design Commission) launches the Adopt-A-Monument program to raise private funds for the conservation and maintenance of public art.

Saving Saint Bartholomew’s Church

MAS successfully appeals a lower court decision that would have allowed the landmark St. Bartholomew’s Church on Park Avenue to demolish its Community House and garden, replacing them with an office tower. The decision affirms the power of the City’s Landmarks Law over sacred sites.

Protecting Public Art through Adopt-A-Mural

Following the success of Adopt-A-Monument, MAS launches its sister program Adopt-A-Mural. Together, the programs have raised more than $5 million to conserve and maintain 51 works of public art across all five boroughs.

Spurring the Creation of Fresh Kills Park

Seeking to increase the city’s parkland, MAS collaborated with New York City in 1999 to sponsor an international design competition for the reclamation of Staten Island’s Fresh Kills Landfill, the world’s largest such facility. Built in phases through 2036, the 2,200-acre Fresh Kills Park will be almost three times the size of Central Park and the largest park developed in New York City in over 100 years.

The Tribute in Light

In the fall of 2001, MAS brings together a team of artists and designers in partnership with Creative Time to create a memorial to the victims of September 11. The Tribute in Light debuted on the six month anniversary of the attacks and MAS continued to produce Tribute in Light each September for the next decade. In 2011, MAS transferred the project to the newly-opened National September 11 Memorial & Museum, which has continued to present it annually on the anniversary of the attacks.

Greening New York City’s Historic Buildings

In partnership with the Landmarks Preservation Commission, MAS publishes Greening New York City’s Historic Buildings, a manual to help property owners and managers improve the energy efficiency of small historic buildings without impacting their character.


Advocates for Privately Owned Public Space (APOPS)

Drawing on over a decade of research, MAS partners with Jerold Kayden to launch APOPS, an advocacy campaign to better activate the city’s 500+ privately owned public spaces. The book builds on Mr. Kayden’s 2000 book, Privately Owned Public Space: The New York Experience, published by MAS.

City Council Votes to Limit Madison Square Garden’s Permit at Penn Station

In the summer of 2013, at the urging of MAS, our partners at Regional Plan Association, and many others, the New York City Council votes to limit Madison Square Garden’s permit to operate on top of Penn Station to just ten more years. The decision represents a historic opportunity to shape the future of Manhattan’s west side and ensure the economic health of the city and the region. Over the next several years, the Penn 2023 coalition would release three reports analyzing the future of Penn, the Garden, and West Midtown.

The Accidental Skyline Project Pulls Back the Veil on Supertalls

MAS releases a first-of-its-kind analysis of the impact of supertall towers, raising the alarm about the need for new rules and regulations to protect public assets like light, air, open space, and the character of the city’s neighborhoods from out-of-scale development. In October 2017, the organization released a follow-up report outlining a detailed agenda for achieving these reforms.

Analyzing the 421-a Tax Exemption

MAS releases a first-ever interactive tool mapping the impact of one of New York City’s most expensive housing incentive programs. The analysis shows that the City forfeited more than $1.1 billion in tax revenue through the program in 2014, 60% of which (nearly $670 million) subsidized buildings in Manhattan.

Mapping the Sixth Borough of New York

MAS releases ground-breaking mapping tool that empowers decision makers, planners, and the public to identify opportunities for improving, protecting, and utilizing the 14,000 properties owned or leased by the City of New York–a public asset roughly the size of the Borough of Brooklyn. The accompanying report reveals that an area more than double the size of Central Park is classified by the city as having no current use.

Sweeping Reforms to the Board of Standards and Appeals

In May 2017, the New York City Council passed a series of reforms to the Board of Standards and Appeals zoning variance process that enact reforms long called for by MAS. In 1976 and 2004, MAS released landmark studies identifying abuse and misuse of the variance process, which effectively resulted in the rezoning of certain communities, without taking into account the cumulative impacts on light and air, traffic, parking, school capacity, and other city services.

Mapping Changes to Historic Properties

MAS creates a pair of interactive maps to inform preservation professionals and members of the public about how the Landmarks Preservation Commission processes and approves applications to modify designated buildings.

Celebrating 125 Years of Advocacy on Behalf of New York and New Yorkers

For 125 years, the Municipal Art Society of New York (MAS) has worked to educate and inspire New Yorkers to engage in the betterment of our city. We hope you will join us in honoring the generations of MAS board, staff, and members whose dedication made these victories possible.

Fight for Light

At the 10th Annual Summit for New York City, MAS and New Yorkers for Parks launch a joint campaign entitled Fight for Light. The initiative seeks stronger protections for sunlight and better planning and management for the public realm to improve the health of New York City residents and address the urgent demands for climate change solutions.

Protecting the Brooklyn Botanic Garden

The City Planning Commission unanimously votes to reject the controversial rezoning application for 960 Franklin Avenue, a 34-story tower in Crown Heights that threatened to cast significant new shadows on the Brooklyn Botanic Garden and Jackie Robinson Playground. The decision followed years of research, modeling, and advocacy by MAS about the devastating impacts the development’s shadows would have on these vital spaces.

Racial Impact Study Legislation is Passed

Approved by the New York City Council and signed by Mayor Bill de Blasio, Local Law 78 of 2021 requires for the first time that applicants include a Racial Equity Report for most rezonings. The report would be evaluated during ULURP using the Equitable Development Data Explorer, which presents publicly accessible, community-level data on housing production and affordability, demographic conditions, and access to opportunity, as well as a citywide Displacement Risk Index map that evaluates population vulnerabilities, housing conditions, and market pressures. For years MAS advocated for the bill’s passage as a member of the Racial Impact Study Coalition alongside the Public Advocate, Jumaane Williams.


New York City Gets a Chief Public Realm Officer

Appointed by Mayor Eric Adams, the Officer is the first such position in the city’s history. The idea for the position originated in MAS’s 2019 Bright Ideas report and was developed and refined in two subsequent MAS reports, A Public Champion for the Public Realm (2020), and A Blueprint for Public Realm Leadership (2022). The appointment is the result of extensive advocacy by MAS as a founding member of the Alliance for Public Space Leadership, a coalition of public space organizations, businesses, conservancies, volunteers, and others that was created in 2022 to ensure equitable public realm solutions and effective management of New York City’s public spaces.
