New York City is huge. 8.4 million people huge to be exact, and, especially in the summer, it can feel like they are all squished directly next you on the subway. If you’re new to the city you might be unaware that just a quick boat ride from Brooklyn Bridge Park there’s a literal island of calm amongst the madness. First “discovered” in the 1600s by Dutch settlers, Governors Island was an important strategic base during the Civil War, and, later in the 20th century, home to the U.S. Coast Guard. In the 90s much of the area was turned into a national park (and occasional summer concert venue), and today those who want a taste of culture sans the lines come to the island to relax, take in the public art, and even catch a few ghosts. Yes! It’s been rumored that parts of the island are haunted—especially the historic Nolan Park area. It’s here that one of the world’s only holographic museums has set up shop for the summer, bringing ephemeral art to match the translucent specters its host destination is known for. Now in its second year, visitors to the Holocenter House will be able to see, touch, and even walk through a wide array of holograms created by some of the pioneers of the art form. A true passion project by its creators, the museum has already succeeded in both turning an otherwise overlooked NYC landmark into a fun (and spooky) summer destination, and promoting while preserving an art form many have overlooked.
