New to Open House New York Weekend this year and trying to plan the perfect itinerary? The roster of sites and tours changes every year, but there are a few long-standing audience favorites that have become must-sees for Weekend participants over the years. Below, we’ve planned a Saturday itinerary that includes visits at several of these “classics.” After your Saturday adventures, you’ll be well prepared to plan your own itinerary on Sunday! All of these sites are Open Access during the times and dates indicated below, and do not require reservations.

Start your day off the headquarters of the Ford Foundation—a pioneering, global social justice philanthropy. Designed by Kevin Roche John Dinkeloo and Associates in 1967, the landmarked atrium is surrounded by exposed granite and Cor-Ten steel. During OHNY Weekend, visitors can take a rare trip up to the balconies overlooking the 12-story atrium to take in a unique view of the indoor terraced garden.

While it is new to OHNY Weekend this year, Porcelanosa has the makings of a new classic. The structure—long known as the Commodore Criterion Building—features a sleek, contemporary interior by starchitect Sir Norman Foster, a skylit top-level design library, and a roof terrace with a jaw-dropping view of the Flatiron Building and Madison Square Park. Don’t miss the chance to explore Porcelanosa with architects from Foster + Partners throughout the day on Saturday (and even return on Sunday for tours with structural engineers from Gilsanz Murray Steficek).

A short walk from Porcelanosa is the headquarters of the Grand Lodge of Free Accepted Masons of the State of New York. The ornate 23rd Street building contains a total of 13 Masonic lodge meeting rooms, each with its own distinctive design and character highlighting some aspect of the history, symbolism or philosophy of the Masonic fraternity.

After your tour of the Masons’ exquisite meeting rooms, take a stroll down to the Jefferson Market Courthouse, now a branch of the New York Public Library, to climb the 149 stairs to the top of the iconic tower that has defined views Sixth Avenue since it was completed in 1875. Due to restricted capacity, long waits are common at this site. Make sure to arrive before 3:00 pm, as the line usually closes early.

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.
