9. Smallest Public Space: Septuagesimo Uno (Or Is it?)

Septuagesimo Uno, the Smallest Park in NYC on the Upper West Side

The space at 256 West 71st Street between Amsterdam and West End avenues is often cited as the smallest public space in New York City. There, between two four-story brownstones, like a short, awkward cousin in a family photo, is Septuagesimo Uno. Calling Septuagesimo Uno a “park” is generous. In fact, the parks department actually calls it a “triangle/plaza.” But Septuagesimo Uno is more like a forgotten dead-end alley that has been reclaimed by Mother Nature. It is a world away from the grand public gathering places (Union Square, Bryant Park, Grand Army Plaza) that we tend to associate with New York City parks. At two-fifths of an acre in size, Septuagesimo Uno could fit into Central Park more than 21,000 times.

But, there are in fact six other parks smaller than Septuagesimo Uno, the smallest being too small to even walk into. Check out McNally Plaza and the other smallest parks of Manhattan here.
