We we’ve detailed in our article on the Top 12 Secrets of the NYC Subway, the Echo Vault has held one of the more incredible urban stunts of recent memory. Led by Wanderlust Projects, the same group of underground events responsible for the Night Heron Speakeasy in a watertower, 200 people climbed down through a hatch in the midst of a busy area of Manhattan and entered an unused station. Lines of what would have become tracks became places to run around and explore. Staircases led to openings that looked down on a central “Echo Vault” on which performances by the Extra Action Marching Band took place. We’re keeping this location mum but all urban explorers know where this is.
