The 1950s and 60s were a period of architectural experimentation, as new materials and technologies opened up a whole range of possibilities for architects and designers. At the time, New York City was in the midst of a post-war construction boom, and today the five boroughs are dotted with some truly amazing masterpieces of Mid-century Modernism. During OHNY Weekend, many of the very best examples from this period will be open to the public, free of charge. From Marcel Breuer’s campus buildings in the Bronx, to Philip Johnson’s very first commission, to a slew of landmarks from the 1964-65 World’s Fair in Queens, fans of Mid-century Modernism (which has been having a moment of late, thanks to the TV show Mad Men) should find this year’s lineup particularly enticing. All of the sites listed below are Open Access during the times and dates indicated below, and do not require reservations.

During OHNY Weekend, visitors will have the rare opportunity to travel up to the balconies overlooking the garden to experience the space from above.

Brooklyn Army Terminal

:00 am6:00 pm.

Once you’ve taken in the sights in Manhattan, hop on the subway and ride out to Sunset Park, Brooklyn, for a rare opportunity to peek inside of the gargantuan atrium of the Brooklyn Army Terminal. Designed by Cass Gilbert (of Woolworth Building fame) and constructed by the military in 1918, BAT served as the largest military supply in the United States through World War II. Today, the site is a thriving commercial and light industrial hub run by the New York City Economic Development Corporation. Free tours will be offered throughout the day on Saturday by the industrial history experts from Turnstile Tours.

By the late 1800s, New York City had become the world’s preeminent seaport. Just a few decades later, it became an early leader in air travel, as well, with the opening of the first municipal airport in the United States in 1931. The city’s history as a hub of international exchange has endowed it with a collection of one-of-a-kind architectural gems that communicate the excitement and optimism of several past “golden ages” of these globe-spanning modes of transportation. Now, as New Yorkers look to the future with the recently announced plans for overhauls at LaGuardia and JFK International Airports, that optimism can inspire and inform our expectations. On OHNY Weekend, visit these sites to see how the architecture of transportation has evolved over time. All of these sites are Open Access during the times and dates indicated below, and do not require reservations.

Building date: 1962 renovation: ongoing Architect: Eero Saarinen Additional: Restoration, Beyer Blinder Belle Architects & Planners

TWA Flight Center

Sunday, October 18: 11:00 am – 3:00 pm.

As anyone who has ever visited it will tell you, TWA Flight Center is a truly magical piece of architecture—a building that captures, in a way that words never could, the exhilaration and wonder of flight. Designed by Eero Saarinen and opened in 1962, this one-of-a-kind structure is now considered a masterpiece of Mid-century Modernism. Visit this OHNY Weekend audience favorite on Sunday, October 18, and get a glimpse of life in the glamorous Jet Age.

In 1811, the Commissioner’s Plan established Manhattan’s street grid from Houston Street (then the city’s northern edge) on up. But bombastic as this act of speculative urban planning may have been, it only went so far—155th Street, to be exact. By the 1860s, planning for the urbanization of Manhattan’s northernmost reaches began in earnest under Andrew Haswell Green’s Central Park Commission. Green extended the numbered grid, but also adapted the streets to the area’s dramatic topography, creating a unique area within Manhattan’s urban fabric, full of charming side streets (quaintly designated as “terraces”), bucolic hillside parks, and stunning vistas. During OHNY Weekend, explore this unique area to learn about a critical moment in the city’s historical development. All of these sites are Open Access during the times and dates indicated below, and do not require reservations.



Morris-Jumel Mansion

Saturday, October 17: 10:00 am – 6:00 pm; Sunday, October 18: 10:00 am – 2:00 pm.

Built by British military officer Roger Morris in 1765, the mansion served as the headquarters for both sides during the American Revolutionary War. Today, the mansion contains one of the few landmark interiors in the five boroughs. Visit during OHNY Weekend to see how wealthy landowners like Stephen Jumel—who bought and remodeled the mansion in 1810—lived in this area at a time before the city had made its way up into the Heights. Tours will be offered on both days.

NYPL Washington Heights Library

Saturday, October 17: 10:30 am4:30 pm.

The Jumel heirs broke up the 115-acre estate surrounding the Morris-Jumel Mansion in 1882, as the re-mapped Heights began to develop in earnest. The area became a fine residential district, (today known as the Jumel Terrace Historic District), and in 1914 a Carnegie Library was built on the edge of the old estate. On the Saturday of OHNY Weekend, tour this Carrère & Hastings-designed structure with Dattner Architects principal Joseph Coppola to learn about the library’s renovation, completed last year just in time to mark the building’s 100th “birthday.”



Hispanic Society of North America

Saturday & Sunday, October 17-18: 12:00 pm4:00 pm.

Named for legendary American naturalist John James Audubon (and sited on a piece of what was once Audubon’s rural estate), historic Audubon Terrace is a monumental, museum-lined plaza tucked into the Manhattan grid between 155th and 156th Streets. Philanthropist Archer Milton Huntington created this impressive City Beautiful-style complex at the height of the Heights’ development—a time when it seemed like the city’s cultural center of gravity might very well be shifting uptown. Today, the complex is anchored by the Hispanic Society of America, a stunning museum and library that will offer free tours on both days of OHNY Weekend.


Randel Map

Manhattan Borough President’s Map Display

Saturday, October 17: 10:00 am4:00 pm.

Before or after you head up to the Heights, don’t miss a very special display of the Randel Farm Maps at the Manhattan Municipal Building downtown, organized and hosted by Manhattan Borough President Gale Brewer. Never before publicly exhibited in full, all 92 panels of the maps—the first that plotted the 1811 Commissioner’s Plan—will be on display during the Saturday of OHNY Weekend. Get feel for how upper Manhattan looked in the days before the grid, when country estates and forested hillsides dominated the local landscape.
