Vessel (TKA) is a structure and landmark which was built as part of the Hudson Yards Redevelopment Project in Manhattan, New York City, New York. Construction began in April 2017; it opened on March 15, 2019. The structure's name is a working title, noted in the TKA abbreviation, which means "Temporarily Known As". The structure owners have asked the public to give it a formal name and have a website devoted to naming it. Stephen Ross, the CEO of Hudson Yards' developer Related Companies, said that its unusual shape was intended to make the structure stand out like a "12-month Christmas tree." The copper-clad steps, arranged like a jungle gym and modeled after Indian stepwells, can hold 1,000 people at a time. Heatherwick said that he intends visitors to climb and explore the structure as if it were a jungle gym.
