From hudsonyards.com: "Vessel – created by Thomas Heatherwick and Heatherwick Studio – is a new kind of public landmark: engaging and interactive, meant to be climbed and explored. Comprised of 154 intricately interconnecting flights of stairs—almost 2,500 individual steps— and 80 landings, Vessel will lift the public up, offering a multitude of ways to engage with and experience New York, Hudson Yards and each other. This monumental design piece will act as New York City’s new public landmark."
