In the midst of this city within a city is one of the most original sculptures in New York: the Vessel. The climbable sculpture, designed by Thomas Heatherwick, looks a little like a pagoda with wings. The soft copper color of its 154 interconnecting staircases shines above a sprawling public garden. With almost 2500 individual steps and 80 landings, there is a mile of pathway within the sculpture. The maze of stairways is like a labyrinth of levels reminiscent of an M.C. Escher painting.
Heatherwick explains the concept behind his sculpture in the video below.
