The borough’s biggest green space hosts everything from the iconic, tulip-ringed Unisphere to the world-famous US Open Tennis Championships. It’s also home to the Queens Museum’s Panorama, an architectural model of all five boroughs (that happens to be the world’s largest), and two time capsules, buried in 1938 and 1965, that contain, among other items, a pack of Camels, an RKO newsreel and a copy of Life magazine. But don’t hold your breath waiting for them to be opened; that won’t happen until the year 6939.
