The Helicoidal Skyscraper was a planned but never materialized 565 meters high business center that was supposed to be built on the tip of Manhattan, NYC. It was a stillborn project developed between 1968 and 1974 by Italian architect Manfredi Nicoletti. It combined its aerodynamic shape with the technology of wired bridges, for the purpose of minimizing both the loads and structural bulk.
