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.

Ford Foundation

Saturday, October 17: 10:00 am – 2:00 pm.

Designed by Kevin Roche John Dinkeloo and Associates, this building’s soaring 12-story atrium looks out over a lush, terraced garden. Though interior spaces built as late as 1985 are eligible for landmark status, the Ford Foundation’s atrium, completed in 1967, is currently the “youngest” interior landmark in the city, and is considered one of the most iconic Mid-Century Modern interiors in the five boroughs. During OHNY Weekend, visitors will have the rare opportunity to travel up to the balconies overlooking the garden to experience the space from above.



Four Seasons Restaurant

12:00 pm4:00 pm.

The Four Seasons has a storied history as the original home of the New York “power lunch,” and is known the world over for its innovative design by Philip Johnson. In fact, it was the famed architect’s first major commission. Visitors will be able to take in a unique view of the surrounding streetscapes through the restaurant’s beloved shimmering chain curtains, and explore the Pool Room, with its four trees that change with the seasons, as well as the Grill Room, with its two iconic Richard Lippold sculptures. An exhibition of images of landmark interiors by photographer Larry Lederman, featured in the new book Interior Landmarks: Treasures of New York, will also be on view.

TWA Flight Center

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

One of the most famous icons of Mid-century Modernism, the TWA Flight Center, is on the National Register of Historic Places. MCR Development, the firm selected by the Port Authority to celebrate Saarinen’s masterpiece and reopen it to the public, is advancing a privately-funded $265 million plan to rehabilitate the national landmark to its original splendor and deliver the first on-site, world-class airport hotel at JFK International Airport. Expected to be complete in 2018, the redevelopment plan will include a museum focusing on New York City as the birthplace of the Jet Age, the storied history of TWA Airlines, and the Mid-century Modern design movement.
